The Distribution and Composition Characteristics of
At the bottom of the sulphide strata, there were conformable tuff strata that overlaid the marine volcanic rocks. As a whole, there were several sedimentary cycles in the Dongxiang ore deposit, and each of the cycles possibly involved marine volcanic rocks, volcanic tuff, metal sulphide, and siliceous rocks from the bottom to the top.

Geochemistry and implication of the Linzizong
The widely spreading Linzizong volcanic succession(LVS)is regarded as the magmatism response to the continental collision between India and Asia,which are essentially important in discovering the initial collisional time and,the present research on LVS is only limited on the typical crosssection of LVS in Linzhou basin to the northeast of Lhasa City,while that in the central

Fractures Types of Volcanic Reservoir and its Significance
Volcanic rock reservoirs have been reported in many locations around the world. The lithologies range from basalt to andesite or rhyolite formed in various geological ages. As a relatively new area in oil and gas exploration, volcanic reservoirs are attracting the attention and interest of scholars in the oil industry. In particular, the discovery of volcanic hydrocarbon reservoirs in China

Formation Mechanisms of Paleogene Igneous
The results indicate that volcanism enhanced the formation of Es 3 source rocks with high TOC (–%) in the distribution areas of igneous rocks. Volcanism caused an abnormal heat field and accelerated the maturation of hydrocarbon source rocks, leading to a higher heat gradient (– °C /100 m), increase of HC and chloroform bitumen "A" contents, earlier hydrocarbon

Origin of the Gacun VolcanicHosted Massive Sulfide
For the volcanic rocks in various alteration zones, a significant increase in δ 18 O value was recorded in the deposit outward from the orebodies and downward from upper to lower volcanic units. The most strongly altered quartzhyalophane zone gave a bulk rock δ 18 O value of to per mil.

A major discovery in Permian volcanic rock gas
The volcanic rock across Chengdu–Jianyang area generally involves the eruptive facies and represents good reservoir belts. The volcanic rock is usually more than 180 m thick and contains multiple primary and secondary reservoir spaces, which lays a good foundation for highquality reservoir development and natural gas accumulation.

Global Volcanism Program | Tengchong
The Tengchong volcanic field, located in southern China near the border with Burma (Myanmar), was active during five periods ranging from the early Pliocene to the Holocene. Three main stages produced Pliocene to midPleistocene basaltic rocks, mid to latePleistocene silicic pyroclastic rocks, and Holocene basaltic andesites. The youngest volcanism in the 600 km2 field occurred in two stages
