盆地基底由前寒武紀結晶基底和古生代褶皺基底組成，盆地蓋層則經歷了二疊紀的裂谷盆地、三疊紀?白堊紀的坳陷盆地和第三紀后的山間盆地的演化過程。盆地主要沉積了下二疊統巨厚火山巖、淺成侵入巖和凝灰巖；中二疊統蘆草溝組的暗色泥巖、泥灰巖、白雲質巖石以及條湖組的巨厚層火山巖、侵入巖；三疊系雜色砂礫巖、砂巖及灰色泥巖（下紅上灰） ；以及侏羅紀厚層深灰、灰色砂礫巖、砂巖、泥巖夾煤層。 -
The main characters of the thermal fluid activity are recognized as follow : many types and stages of veins are widely developed ; vitrinite reflectivity of different areas varies apparently with the depth ; there was a high temperature field during the formation of the thermal fluid, meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff ; in the tufaceous mud, the thermal fluid activity accelerates " maturating " of the organic carbon by heating ; and the trace elements show an anomaly in the wall rocks
同時，受熱流體活動的影響，熱流體對火山碎屑巖具有一定改造作用，如在安山質巖屑凝灰巖中，斜長石絹雲母化、火山巖巖屑綠泥石化明顯；在凝灰質泥巖中，熱流體對圍巖中有機碳具有明顯的「催熟」加熱作用，微量元素則出現異常現象。 -
