近年来,我队先后在吉安盆地、袁水凹陷、信江凹陷等有第三系和白垩系红色岩层(简称红层)掩盖的地区,进行了电测普查找煤工作。兹将我们对红层掩盖区物探找煤工作的认识和体会加以介绍。一、红层的地电特征红层的地貌特征,有些是被第四系覆盖的平原,有些是高数十米到一百米左右的小山 In recent years, our team successively carried out the electric survey and coal prospecting work in areas covered by Tertiary and Cretaceous red rock formations (referred to as the red beds), such as the Ji’an Basin, Yuanshui Depression and the Xinjiang Depression. Hereby, we will introduce our understanding and experience of looking for coal in the red layer covered area. First, the geoelectric characteristics of the red layer The geomorphological features of the red layer, some are covered by the Quaternary plain, and some are tens to hundreds of meters high hill
