Metallogenic models of cu , ag deposits in felsic volcanic rock of permian continental facies of awulale , western tianshan mt 西天山阿吾拉勒二叠纪陆相长英质火山岩铜银矿矿床模式
2.
They were marine basins before carboniferous , and evolved into continental basins after triassic by transformation from the marine facies into the continental facies in permian 同样,在储集条件方面,中国类前陆盆地除发育海相储集层外,还广泛分布陆相储集层。

The basins in west china were downfaulted depression basins in jurassic and cretaceous , and foreland basins in cenozoic . these basins formed not only marine facies source rocks ( oil type ) and reservoirs but also continental facies source rocks ( coal type and oil type ) and reservoirs 因此,中国类前陆盆地基本石油地质条件与国外富油气前陆盆地相比,除海相烃源岩的质量不及后者外,其它方面并无明显不足,且具有发育陆相烃源岩和储集岩的优势。
