江南古陆横贯黔、湘、赣诸省,是我国南方的重要产金地。广大地质工作者长期以来的找矿实践,认为江南古陆与黄金资源在“控矿”上有着某些专属性,并常常被理解为古陆前震旦系变质岩与其中的变质热液金矿床(广义的层控金矿床)的专属关系,并就目前已发现的数百个金矿床(点)中,几乎毫无例外地证实了上述认识。近年来,随着找矿活动的加强,在古陆边缘的湖北崇阳发现了新的金矿床(点)。1986年,武警黄金十六支队,通过砂金群采提供的找矿信息,在江南古陆中段北缘的江西土龙山,又找到一个与传统“古陆型”金矿特点大不相同的金矿床,从而为在江南古陆找金开辟了新
Jiangnan ancient land across Guizhou, Hunan and Jiangxi provinces, is an important gold production in southern China. The geologists have long been looking for ore-bearing practices. They think that the ancient Jiangnan land and the gold resources have certain specialties in “controlling the ore” and are often understood as the former Sinian metamorphic rocks and the metamorphic hydrothermal gold deposits (Generalized stratified controlled gold deposit), and almost no exception has been confirmed in the hundreds of gold deposits that have been discovered so far. In recent years, with the strengthening of prospecting activities, new gold deposits have been discovered in Chongyang, Hubei Province, on the edge of the ancient land. In 1986, the 16th Brigade of the Armed Police Forces, through the prospecting information provided by the goldmine group, found a gold deposit that is very different from the characteristics of the traditional “paleo-continental” gold deposits in the Tu Longshan, Jiangxi Province, on the northern margin of the middle section of the Jiangnan Old Continent , So as to find a new ancient gold in the southern Yangtze River
