tufaceous
解釋
凝灰質的-
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。
