Abstract Jiama is the largest porphyry-skarn ore system in Gangdese metallogenic belt, Tibet. It composed of porphyry Cu-Mo, Cu-polymetallic skarn, Cu-Pb-Zn manto, and distal vein Au orebodies with associated Ag, W, Bi. However, precise timing magmatism hydrothermal events at remains obscure. Here, using high-precision chemical abrasion-isotope dilution-thermal ionization mass spectrometry (CA-ID-TIMS) U-Pb zircon dating ore-bearing post-ore intrusions, we accurately constrain lifespan...
Abstract The Tiegelongnan Cu (Au) deposit is the largest copper newly discovered in Bangong–Nujiang metallogenic belt. has a clear alteration zoning consisting of, from core to margin, potassic propylitic, superimposed by phyllic and advanced argillic alteration. shallow part of consists high sulphidation‐state overprint, mainly comprising disseminated pyrite Cu–S minerals such as bornite, covellite, digenite, enargite. At depth porphyry‐type mineralization comprises chalcopyrite, pyrite,...
Abstract The Tiegelongnan deposit is a newly discovered super‐large porphyry‐epithermal Cu‐(Au) in the western part of Bangong Co‐Nujiang metallogenic belt, Tibet (China). Field geology and geochronology indicate that porphyry mineralization was closely related to Early Cretaceous intermediate‐felsic intrusions (ca. 123–120 Ma). Various epithermal ore gangue mineral types were middle‐shallow orebody, indicating presence at Tiegelongnan. Potassic, propylitic, phyllic advanced argillic...
The newly discovered Tiegelongnan Cu (Au) deposit is a giant porphyry overprinted by high-sulfidation epithermal in the western part of Bangong–Nujiang metallogenic belt, Duolong district, central Tibet. It mainly controlled tectonic movement Oceanic Plate (post-subduction extension). After closure Ocean, intrusions emplaced at around 121 Ma area, which might be result continental crust thickening and collision Qiangtang Lhasa terranes, based on crustal radiogenic isotopic signature....
班公湖-怒江洋的形成演化是认识班公湖-怒江成矿带成矿地质背景的关键，近几年中国地质调查局在青藏高原部署了大量1：50000区域地质调查工作，取得了很多重要发现。对班公湖-怒江结合带两侧关键性海陆沉积地层对比研究，认为南羌塘地块与拉萨地块晚古生代-晚三叠世地层沉积特征及岩石组合基本一致，二者在班公湖-怒江中生代洋盆形成以前是一个整体，为冈瓦纳大陆北缘被动陆缘环境。班公湖-怒江洋在早中侏罗世裂解形成，至中侏罗世趋于稳定且范围最大；向北俯冲消减作用始于中晚侏罗世，晚侏罗世-早白垩世演化为残留海，早白垩世中晚期出现短暂的裂解，致使海水重新灌入；晚白垩世班公湖-怒江洋盆进入闭合后的隆升造山阶段，发生了残留盆地迁移，形成了磨拉石建造。班公湖-怒江洋类似古加勒比海（现今墨西哥湾地区）的形成机制，并与大西洋、太平洋的形成过程关系密切。对于班公湖-怒江洋的闭合和冈底斯弧的形成，本文提出了另一种可能解释，即，新特提斯洋向北俯冲下，岩浆弧逐步南迁，在弧后形成了一系列伸展性质的弧后盆地，两者组成微陆块由北向南逐渐增生形成了现今的拉萨地体，持续向北俯冲也导致了班公湖-怒江洋最终闭合。
Many large and super-large copper deposits have been discovered explored in the Tibet Plateau, which makes it most important resource reserve development base China. Based on work of research team, paper summarizes geological characteristics main puts forward a further prospecting direction. A series accumulated metal or ore districts from subduction Tethys oceanic crust to India-Asia collisionhave discovered, such as Duolong Cu (Au) district Jiama polymetallic deposit. The are located...
The study area, Duolong mineral district, Tibet, China is not a well-developed area but has received attention in recent years due to its considerable production of Cu-Au resources. This paper utilizes fractal/multifractal analytical techniques gain insights the geological environment, metallogenesis ore deposits, as well exploration this area. Porphyry mineralization related elements and fault-activity indicator from stream sediments geochemical data are integrated by log-ratio...
Abstract:
In classic orogenic models, the mountain range is underlain by a deep crustal root. Here we present and upper mantle structures along two receiver function profiles across Qilian, an orogen experiencing recent growth at northern margin of Tibetan plateau. Opposite to expected root beneath orogen, Moho Qilian arch-like, shallower center deepens up 10 km its southern boundaries. Additional velocity interfaces sub-parallel are observed in lower crust basins south which interpret as top...
This article reports new zircon laser ablation-multicollector-inductively coupled plasma-mass spectrometry U–Pb and Hf isotope, whole-rock major trace element, Sr–Nd isotope data for mineralized barren intrusions associated with the Duolong porphyry–epithermal copper–(gold) deposit (DPCD, a mining camp containing several individual deposits) in western Qiangtang Terrane (QT), central Tibet. These are used to further our understanding of geological evolution this region. The DPCD typical...
Rutile is a common and stable mineral in porphyry Cu deposits, morphology geochemistry of rutile are recognized as potential indicator for exploration. In this study, we investigate physical features chemical composition hydrothermal the Tiegelongnan porphyry-epithermal system, well stream sediments nearby to establish method apply an exploration proxy. Four stages have been identified. Potassic alteration stage (Rt1) associated with biotite, elongated acicular shape small grain size (20–50...
