Structural evolution characteristics and hydrocarbon accumulation of Jinma-Yazihe area

Youqicang pingjia yu kaifa, 2020
Jinma-Yazihe area is located at the junction of Longmenshan fold-thrust belt and Sichuan basin. Based on the 3D seismic data, the characteristics of faults and the process of tectonic evolution are analyzed.

Geological Knowledge‐Guided Dual‐Branch Deep Learning Model for Identification of Geochemical Anomalies Related to Mineralization

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract Geochemical survey data are a type of spatial big data that play an increasingly significant role in mineral exploration. One challenge in the era of big data is how to mine geochemical data in support of mineral exploration. In this study, based on a generative adversarial network framework, we proposed an unsupervised spatial–spectrum dual ...

Relationship between gas reservoir distribution and structural system of upper Triassic Xujiahe Fm in the Sichuan Basin

Natural Gas Industry B, 2019
The gas reservoir of Upper Triassic Xujiahe Fm in the Sichuan Basin is characterized by “accumulation in the early stage, entrapment in the middle stage and activation in the late stage”.

Some causes and consequences of lithospheric thinning in the eastern North China Craton : evidence from latest Yanshanian granitoids and dykes [PDF]

, 2010
The lithosphere beneath the eastern part of the North China Craton (NCC) is known to have been thick (> 200 km) during the Early Palaeozoic as manifested by the presence of diamondiferous kimberlites (Menzies et al., 1993; Griffin et al., 1998; Yang et ...

Formation and destruction mechanism as well as major controlling factors of the Silurian shale gas overpressure in the Sichuan Basin, China

Journal of Natural Gas Geoscience, 2016
Taking the Well JY1 and Well PY1 in the Eastern Sichuan Basin as examples, the formation mechanism of shale gas overpressure was studied by using the cross plot of acoustic versus density logging data.

Thermotectonic history of SE China since the Late Mesozoic: insights from detailed thermochronological studies of Hong Kong

, 2016
The late Mesozoic Yanshanian volcanic arc affected an extensive region of SE China, but the conclusion of magmatism and later evolution are not fully understood.

Geochemical Characteristics and Water Content of Melt Inclusions in the Tuff of the Tiaojishan Formation, Liujiang Basin

Yankuang ceshi
Water, as the primary volatile component in magmatic systems, has a significant impact on the formation and evolution of magma. The Tiaojishan Formation igneous rocks in the Liujiang Basin are significant products of Yanshanian volcanic activity ...

Geochronological, whole-rock elemental and Sr-Nd isotopic and apatite geochemical studies of Early Yanshanian (Jurassic) intrusives from Nanling Mountains area, South China and their tectonic implications

, 2010
在華南廣泛出露的中生代侵入岩主要形成於三個時期：三疊紀（印支期）、侏羅紀（早燕山期）及白堊紀（晚燕山期）。岩性上來說，岩漿產物以酸性的花崗岩為主；在體積上，則以早燕山期岩漿活動最為強烈，產生的花崗岩占了中生代花崗岩近一半的出露面積。本研究針對南嶺地區的早燕山期侵入岩，分析鋯石鈾－鉛年齡、全岩與磷灰石地球化學及鍶－釹同位素組成，以討論早燕山期侵入岩的時空分佈與岩石成因。除此之外，還量測了南嶺地區的早燕山期花崗岩體型態，藉此瞭解花崗岩體與區域滑移斷層的關連，最後結合所有資料推論出華南中生代之地體構造演化。
