在新西兰戈尔登克罗斯(Golden Cross)原热液活动区内有一负剩余重力异常,最小值为-40g.u.该负重力异常是由热液蚀变作用导致蚀变带内质量亏损造成的。并用重力模拟法(正演方法)来确定热液蚀变带的横向、倾向延伸和分布范围。鉴于该区还有一些有价值的金一银矿与硅化、粘土化等蚀变有关,所以应用此法还是有效果的。 There is a negative residual gravity anomaly in the area of ​​the original hydrothermal activity in Golden Cross, New Zealand, with a minimum of -40 g.u. This negative gravity anomaly is caused by a loss of mass within the alteration zone caused by hydrothermal alteration of. Gravity simulation method (forward method) was used to determine the extensional and extensional extents of hydrothermal alteration zones. In view of the area there are some valuable gold and silver and silicification, clay and other alterations, so the application of this method is still effective.
