摘要
利用二维重力正演拟合的方法，导出湖北武当山地区地下地层的可能分布，认为该地区是老地层覆盖在新地层之上，从而佐证了推覆体的存在。同时还得出：在川陕鄂地区的地壳中普遍存在低密度体，该低密度体可能是麻粒岩受压后析出自由水发生破碎所致。
The probable shape of the subsurface strata of the Wudang Mountain area of Hubei is calculated by the method of two-dimensional gravity modeling. In this area,the old strata overlie the new strata, so that,the existential probability of the nappe is certified. Simucltaneously it is certified that the low density body generally exists on the crust of Sichuan, Shanxi and Hubei area. Perhaps this low density body is composed of broken granoblastic.
