条湖组的分布范围与芦草沟组大致相当，但岩性却差异很大，为厚层中?基性火山岩、火山碎屑岩，是火山活动频繁的证据，条湖组沉积岩夹在火山岩中间，主要为灰绿、紫红色泥岩、砂岩及砂砾岩。 - Permian series distributed widely in the baisin . lower permian series was composed of acid , neutral , and basic volcanics , subvolcanic rocks , volcanoclastic rocks and few normal sedimentary rocks . from western to eastern , the volcanics transited from acid volcanics to neutral and basic volcanics

结果认为，白垩纪火山岩以中酸性火山熔岩和火山碎屑岩为主，局部发育基性熔岩；中酸性火山岩以钙碱性系列为主，形成于挤压造山环境，储集性能较好，而白垩纪基性熔岩以碱性系列为主，形成于裂谷环境，储集性能较差。
