The petrogenesis of intrusive rocks is discussed in this paper according to the equilibrium of minerals. It is suggests that in the Shigujian pluton, the designations of plagioclases are 15 - 25, the plagioclases are all oligoclase; the biotites are Mg-biotites, and most of the amphiboles are edenitic amphiboles or edenite; paragenetic ...

结果表明：（1）石鼓尖侵入岩中，斜长石成分较稳定，共生角门石和黑云母为岩浆平衡结晶的矿物；（2）天堂寨和九资河侵入岩中，部分斜长石和黑云母可能为熔蚀残留矿物，角闪石属于火成岩区的新生矿物，可能为斜长石和黑云母发生熔融反应所形成；（3）三个侵入体的岩石均为岩浆成因。

Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.

文章选取云英岩型矿体及上部石英脉型钨矿体中与黑钨矿共生的辉钼矿7件，进行Re-Os等时线年龄测定，得到其模式年龄为(141.4±2.2) Ma~(158.2±2.2)Ma，其中云英型钨锡矿体中辉钼矿等时线年龄为(156.8±3.9)Ma，成矿时代为中侏罗世，对应于燕山早期第二阶段；从云英岩矿体中样品模式年龄为(150.7±2.4)Ma~(158.2±2.2)Ma，石英脉型矿体中样品模式年龄为(141.4±2.2)Ma~(151.0±2.4)Ma。

Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.
