遥感资料特点及应用

THE STRATIGRAPHIC HORIZON AND ITS AGE AT XISHAN, BEI AN VILLAGE, CENTRAL JILIN AREA

遥感资料是根据电磁波原理,将地质体的波谱特性记录在图象上或磁带上的一种资料。应用遥感资料进行地质调查和研究是一种新的工作方法和手段。本文拟对遥感资料的三个主要特点及应用进行论述,这对发挥遥感资料在地质工作中的作用是有好处的。

In 1973, limestone in the Bei An village was incorporated into a part of the Shoushangou Formation by professor Tao Nansheng. In fact, it is a large lens consisting of limestone and pyroclastic in the Bei An village, which occurred in the uppper part of the Daheshen Formation of early Permian. Coral, fusulinida, brachypoda and bryozoa are found at the Xishan Bei An village, i.e.Lytrolasma sp., Tachylasma stereoseptatum, Cyathocarinia taberculata, Lophophyllidium cf. crassiseptatum, Waagenophyllum stereoseptatum, Szechuanophyllum szechuanesse; Neoschwagerina simplex, Chusenella sinesis, Schwagerina kwangchiensis; Neospirifer ravana, Liosotella spitzbergiana, Dictyoclostas cf. bayanghuensis etc.. This assemblage indicates that it is early Permian in age (early stage of early Permian-late stage of early Permian). So, the Xishaa formation in the Bei An village should belong to early Permian Daheshen Formation.
