集块岩

西秦岭甘肃天水地区分布的新生代陆相中酸性火山岩，主要由流纹岩、部分流纹质熔结（角砾）凝灰岩及少量角砾凝灰岩、火山集块岩等组成。

There are Cenozoic continental intermediate and acid volcanic rocks in the Tianshui area , western Qinling . The rocks are mainly composed of rhyolite , parts of rhyolitic ignimbrite ( breccia tuff ), a little amount of breccia tuff and volcanic agglomerate .

在剖面上，与变质玄武岩整合接触的巨厚的变砂岩和大量出现的火山角砾岩和集块岩是浅海环境的标志；

Thick metasandstone and a lot of volcanic breccia and agglomerate in section indicate a shallow marine setting .

集块岩主要孔隙类型为炸裂缝和基质内气孔，孔隙和裂缝明显受后期成岩作用的改造。

The pore and fracture are obviously reformed by post-diagenesis .

在熔岩或集块岩上有渗漏中心存在。

There are infiltration center on lava and agglomerates .

层位较昂格鲁克岩流为高的马却多多普凝灰岩及集块岩，只见于德兰士瓦东部。

The Machadodorp tuff and agglomerate , which is higher-lying than the Ongeluck lave , is known only from the Eastern Transvaal .

沉积后期成岩作用的不均一性是造成各类储集层平面不连续分布特征的主要因素。集块岩主要孔隙类型为炸裂缝和基质内气孔，孔隙和裂缝明显受后期成岩作用的改造。

Moreover , the heterogeneity characteristics of post sedimentary diagenesis caused the isolated and discontinuous planar distribution of all types of reservoir . The pore and fracture are obviously reformed by post-diagenesis .

在远得没法分辨的地方——也不知究竟是一里还是一百万里，当然也可能是他眼睛里的一粒灰——有座让人目瞪口呆的高山直入云霄，最后散成了鹭羽，集块岩和修院长。

Way off in some indistinguishable distance - was it a mile or a million or a mote in his eye ? - was a stunning peak that overarched the sky , climbed and climbed and spread out in flowering aigrettes , agglomerates , and archimandrites .
