英文摘要	东准噶尔卡拉麦里大气田的主要储层是石炭纪火山岩,石炭纪古火山机构的样式与组合特征,与火山岩储层展布关系密切。野外调查表明,隐爆角砾岩是东准噶尔石炭纪古火山机构最常见的标志之一。东准噶尔石炭纪古火山机构类型主要有中心式、裂隙式和裂隙-中心式等样式。中心式火山机构以大石头层状火山、柯克巴斯套锥状火山最为典型;巴塔玛依内山附近沿断裂分布的带状火山岩具有裂隙式喷发的特征;东黑山火山具有火山口串珠状排列特征,是裂隙-中心式喷发的产物。大石头地区原缪林托凯陶山组火山岩的锆石SHRIMP U-Pb年龄为345.6±7.1 Ma,而已知巴塔玛依内山组火山岩年龄是350.0±6.3Ma,因此东准噶尔火山活动的主...; Carboniferous volcanic rocks are the main reservoirs of giant gas field of Kalamarly in eastern Junggar There is a close relationship between the types and assemblage characteristics of Carboniferous volcanic edifice and the distribution of the volcanic reservoir Field survey indicates crypto-explosive breccia is the mark of Carboniferous volcanic edifice The volcano types are grouped into central volcano, fissural volcano and fissural-central volcano in eastern Junngar Daslutou stratovolcanoes and Kekebasitao scoria cones are the representatives of the central volcano The belt volcanic rocks along the fault near Batamaymeishan present the characteristics of fissrural volcano. Dongheishan volcanoes, arranged in cone-row, are the products of the fissural-central eruption. The SHRIMP U-Pb dating of volcanic rocks from the former Miaolintuokaitaoshan Group in Dashitou area is 345. 6 +/- 7. 1Ma, while the age of Batamaymeishan Group published is 350 0 +/- 6 3Ma. Therefore Early Carboniferous is the main stage of the volcanic eruption in eastern Junggar; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000275734400008&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 5; 02; 440-448; 26
