The Geology Of The Sinai Desert


Post by Steve Phillips








"The change from sandstone to granite as one leaves Jebel Mukatteb and winds along Wady Feiran is quite striking. Even to the most uneducated eye the colours tell their own story of chalk and limestone and sandstone and granite. The mountains are streaked from head to foot as if boiling streams of dark red matter poured over them, the vast heaps of seemingly calcined mountains, the detritus iron in The sandstone formation, the traces of igneous action on the granite rocks are dating from their initial upheaval" Sir Charles Wilson, Picturesque Palestine.

The Sinai peninsula is enclosed by the two spectacular branches of the African Rift Valley - the Gulfs of Aqaba and Suez. Since at least 25 million years ago these, and numerous related rift faults in the interior of the peninsula, have played a dominant role in the geological evolution of Sinai. The total location of the Sinai is 61,200 sq km. Sinai is the crossroads between Asia and Africa on the one hand, and the Mediterranean and the Indian Ocean on the other. The peninsula can conveniently be divided into a northern and a southern region.

The North consists of flat lying Palaeozoic and more recent sediments, while the South consists essentially of metamorphic and magmatic rocks which are of pre-Cambrian age. This southern portion is a continuation of the Arablo-Nubian Desert.

The central Et-Tih plateau of Sinai is virtually unpopulated, but at the foot of Et Tih to the south are the wide sand plains. In rainy years they present some pasture and are simpler to traverse. This narrow belt (30 km wide) of soft Nubian sandstone also contains most of the Sinai minerals, e.g., turquoise, manganese, copper. Below this sandstone belt the granite mountains appear, rising to peaks of far more than 7,000 feet. This location has water, stunning oases and numerous gardens. Some of the valleys carry water all year round.

The metamorphic rocks in Sinai were last active about a thousand million years ago. At that time along the Eastern portion of Sinai, a north-south belt of volcanic islands were active following their deposition as ancient marine sediments in a wonderful oceanic basin, As a result, huge quantities of lava accumulated in this region at the same time as other assorted sediments had been deposited in adjoining basins due to erosion. At a later date, widespread intrusion of granite batholiths and plutons took location.

This resistant rock now occupies some 60% of the southern part of the peninsula and is responsible for the most magnificent peaks (Gebel Serbal) and deepest canyons (Dahab). There had been a number of periods of intrusion and dyke swarms before a brief burst of younger volcanic activity, e.g., Gebel Musa and Catherine.

Chinese scientists have found genetic mutation common mechanism - Mud Pump - Geological Drilling Rig


Write-up by hi joiney








In the colorful life of the world, what causes the diversity of life developing appealing? Soon after years of painstaking research professor at Nanjing University boldly created "Indel mutation hypothesis", with the newly discovered "universal mechanism of genetic mutation," cracked the biology of several suspense. July 20, the latest issue of "Nature" magazine published in Nanjing University to total this independent investigation.In the "natural" "published in eukaryotes insertion / deletion mutations increase the rate of the surrounding sequences," the paper, College of Life Science, Nanjing University, Professor Tian Dacheng, Chen and other independent groups and several drafts to total wisdom.Considering that 2005, their bio-informatics technology by human, chimpanzee, rhesus monkeys, mice, fruit flies, such as rice and distinct kinds of yeast genome sequences were compared to the analysis. Investigation found, DNA insertion / deletion (Indel) will trigger a series of variations around. On this basis, they proposed "Indel mechanism of spontaneous mutation induction hypothesis", the success from the source to answer the "how the genetic variation of the formation of" the fundamental issues facing the life sciences. The hypothesis that the genome of diverse species can be utilised for reference frame to be tested, and received the support of a variety of test results.Tian Dacheng explained that the mutations primarily refers to the nucleotide sequence of DNA, kind and quantity of alter, and DNA sequence widespread point (bp) mutation is the fundamental source of genetic variation. Point mutations are divided into spontaneous mutation and induced mutation. For a lengthy time, the academic program of the classical understanding of spontaneous mutation is spontaneous mutations by a quantity of aspects, the result is a series of modifications, with the randomness and rarity. But as the last century because the 90's DNA sequencing technology breakthrough, the researchers of the spontaneous mutations in the genome with the number and distribution of accurate estimates, and normally considered the "spontaneous mutations in the genome are not randomly distributed, the mutation Hot widespread in the genome. " This conclusion of the spontaneous mutation of conventional understanding of randomness and rarity, tremendous challenge, and this phenomenon has caused great concern amongst scientists, but sadly has not found a general mechanism to explain this major scientific questions.Tian Dacheng and other genetic mutations discovered a new mechanism is of excellent scientific significance, successfully cracked a lot of suspense on biological genetics: first, all regions of the genome mutation rate is really various, the number of spontaneous mutation is the quantity and density of the Indel decision, the number of spontaneous mutations are not rare in Indel near, far away from Indel region is rare, but Indel itself is a point mutation, its occurrence has some randomness, so the induced mutations also have a particular randomness Second, find the source of the majority of spontaneous mutation, ie, biological diversity, the initial source of variation is mainly induced by the Indel Third, natural selection to a huge extent by the option of the Indel implementation The level of spontaneous mutation rate is largely the result of natural selection Fourth, biological variation via the ability to regulate their own capacity to adapt to the environment than people originally expected, although, that the role of mutations in evolution enormous.The outcomes not only lead to a significant number of scientific issues, also has prospective applications, such as the somatic cells of the Indel mutation effects may be the key to unlock the mechanism of tumor huge Indel overall mutation effects, understanding the origin of life play an important role Indel amplification mutation heterozygote effect, the mutation rate can considerably enhance the genetic breeding of crops have substantial potential value.

Give full play to the role of central enterprises the full support of the backbone of stable develop


Write-up by jekky








In the 17 to 19 May and held a central Xinjiang Symposium, group general manager, party secretary Jiang Jiemin to speak on behalf of PetroChina, pledged to seriously implement the spirit of the meeting and make every effort to support the work of Xinjiang's development, give full play to The key role of central enterprises to accelerate oil and gas development in the Xinjiang region, to promote the development of Xinjiang's stability and unity to make a positive contribution. Jiang Jiemin said that the central function conference in Xinjiang, Xinjiang to further clarify the trigger of the party and state function in the overall development of the critical strategic position, has deepened our new situation and to promote lengthy-term stability of Xinjiang by leaps and bounds of unique significance to the understanding of a lot more enhanced our support of key state enterprises sense of urgency and responsibility in the development of Xinjiang. China Petroleum and need to conscientiously implement the spirit of the meeting and make each effort to support the development of the function in Xinjiang, give full play to the role of the central backbone enterprises, to protect national energy security and promote stable development of Xinjiang, and make positive contributions to national unity. Jiang Jiemin said that a lengthy time, China has to speed up Xinjiang Petroleum oil and gas development as the central authorities concerning the function of the overall deployment and Xinjiang's western region development technique, an crucial measure, in the Xinjiang oil and gas enterprise has sustained rapid growth. Currently, the Tarim Oilfield, Xinjiang Oilfield, Turpan-Hami Oilfield and Dushanzi, Urumqi Petrochemical, and pipelines, sale, transportation, engineering and technical services 11 companies. Nearly 30 years, China has invested oil in Xinjiang far more than three,000 billion yuan, 18 million tons of crude oil formed / year, 23 billion cubic meters of natural gas / year, processing 20 million tons of crude oil / year and ethylene 1.2 million tons / year production capacity. 2009 operating income 217.4 billion yuan, 27.2 billion yuan turned over to the tax. As of the end of 2009, has geological reserves of three billion tons of proven oil and natural gas geological reserves of 1.three trillion cubic meters, with the further development of the resource base. Dushanzi 10 million tons put into production in million tons of oil refining and ethylene project, to turn into the largest refinery in Western integration projects to promote economic and social development in Xinjiang has played an critical role. In the development of oil and gas business, China's oil active counterpart support work in Xinjiang, investment and construction of water conservancy, electric power, transportation, environment and other projects. Given that 1994, PetroChina Xinjiang six counties to implement fixed-point pro-poor, total invested a billion dollars, the training of cadres and technicians poor a thousand farmers and herdsmen, so that assist the poor counties had achieved "an improve by double," the obvious effectiveness of the farmers and herdsmen's per capita net income and revenue more than quadrupled. Jiang Jiemin said that because the beginning of this year, the Chinese central government's series of oil in accordance with the decisions and deployments to accelerate oil and gas development in Xinjiang has carried out a special study to develop a development plan and construction plan. The next 10 years, to continue to improve investment, the Xinjiang create the largest production base of oil and gas, refining and chemical industry base, the oil reserve base, engineering services, support bases. Oil equivalent in 2015 to reach 50 million tons, more than 60 million tons by 2020 and strive to continue stable for 20 years, refining capacity to 26 million tons, respectively / year and 30 million tons / year, improved oil sales network, to protect the marketplace supply. Speed up the strategic oil reserve and the creating of the western strategy. Construction of two gas pipelines in Central Asia and other natural gas pipeline projects, complete and perfect the Sino-Kazakhstan oil pipeline to Xinjiang coal gas and oil and gas resources of Central Asia and Russia into economic benefit. Continue to boost service support capability, and built to protect the western base of engineering and technical services to create a a lot more comprehensive security system provider, to support nearby development to extend the industrial chemical. Jiang Jiemin said, in Xinjiang the development of new historical period, we need to inherit and carry forward the brave, the courage to win an attempt to develop unity and prosperity of the great tradition of enterprise development, promoting local economic development, supporting improved oil infrastructure, and strive to build a harmonious mining petroleum and petrochemical, to protect the ecological environment for the benefit of local people. Continue to do the unit-designated poverty alleviation, boost economic, technological and personnel Yuan Jiang, and boost self-development ability of the recipient area.
