Geology - Study Results from University of Delhi Provide New Insights into Geology
2013 JUN 18 (VerticalNews) -- By a News Reporter-Staff News Editor at India Business Newsweekly -- A new study on Geology is now available. According to news originating from Delhi, India, by VerticalNews correspondents, research stated, "Models for the origin and deformation of Himalayan rocks are dependent upon geometric and age relationships between major units. We present field mapping and U-Pb dating of igneous and detrital zircons that establish the lithostratigraphic architecture of the eastern Himalaya, revealing that: (1) the South Tibet detachment along the Bhutan-China border is a top-to-the-north ductile shear zone; (2) Late Triassic and Early Cretaceous sedimentary samples from the northern Indian margin show a similar age range of detrital zircons from ca. 3500 Ma to ca. 200 Ma, but the Late Triassic rocks are distinguished by a significant age cluster between ca. 280 and ca. 220 Ma and a well-defined age peak at ca. 570 Ma, (3) an augen gneiss in the South Tibet detachment shear zone in southeast Tibet has a Cambrian-Ordovician crystallization age, (4) Main Central thrust hanging-wall paragneiss and footwall quartzites from the far western Arunachal Himalaya share similar provenance and Late Proterozoic maximum depositional ages, and (5) Main Central thrust footwall metagraywacke from the central western Arunachal Himalaya has a Paleoproterozoic maximum depositional age, indicated by a single prominent age peak of ca. 1780 Ma. ...read more
Geology - Findings in Geology Reported from I. Patra and Co-Researchers
2013 MAY 28 (VerticalNews) -- By a News Reporter-Staff News Editor at Journal of India -- Investigators discuss new findings in Geology. According to news reporting out of Andhra Pradesh, India, by VerticalNews editors, research stated, "The Mesoproterozoic Khariar basin, to the SE of Chhattisgarh basin, comprises 1000 m thick arenaceous-argillaceous sediments. For the first time, a multidisciplinary approach has been made to the integrate interpreted satellite imagery, aero-magnetic and aero-radiometric data with available ground exploration data sets with an objective to understand structural fabric and to establish various parameters for unconformity related uranium mineralization in the environs of Khariar basin. ...read more
Geology - Report Summarizes Geology Study Findings from Jadavpur University
2013 MAY 7 (VerticalNews) -- By a News Reporter-Staff News Editor at Journal of India -- Fresh data on Geology are presented in a new report. According to news reporting from Calcutta, India, by VerticalNews journalists, research stated, "An attempt is made to map the spatial variation of the tectonic stress pattern in northeast India and its adjoining south Asia region using stress tensor inversion of some 516 fault-plane solutions. The Bhutan Himalaya and the Arunachal Himalaya are mapped with north-south to north-northwest-south-southeast compression. ...read more
