lava breccia
volcanic breccia
volcanic breccia
- 准噶尔盆地火山岩储层物性一般特点是：酸性熔岩、火山角砾岩最好，特别是经后期构造运动和溶蚀作用改造后的火山角砾岩；安山岩的物性总体优于玄武岩。
The petrophysical properties of volcanic rock reservoirs in Junggar Basin are generally characterized by the following: the acidic lava and auto brecciated lava are the best, especially the petrophysical properties of auto brecciated lava and andesites after the tectonic movement and denudation process in the later stages are superior to those of basalts. - 本人概略介绍了其矿床地质特征、研究现状及其新进展，并明确提出了该类型金矿床的成矿与中新生代火山-次火山(隐爆角砾岩)作用、构造运动及有机质的作用息息相关。
Primarily summerization on geological characteristics and new progress in scientific research of these deposits are given in this paper, the author proposes that mineralogenesis of MPCD type gold deposit is closely related to Meso-Neozoic volcanic-subvolcanic action (cryptoexplosive breccia), tectonic movement and maturation of organic material. - 根据其金矿成矿物质来源、成矿作用及产出的围岩条件可划分为火山热液型、次火山－浅成斑岩热液型和隐爆角砾岩型金矿床。
Based on the derivation of metallogenic matters, mineralization and wallrock conditions, the gold deposits are subdivided into three main types: volcanic thermal type, subvolcanic rock-shallow to ultra-shallow porphyry thermal type, and concealed explosive breccia type of gold deposits.
