李坊重晶石矿床发现十多年了,但探明是特大型富矿还是近年地质一队普查勘探的结果。这一发现,引起了中外地质界、矿业界的重视,对矿床的成因也先后提出一些不同的看法,大体有热液说、顺层交代说、沉积说等。一九八一年福州大学地矿系师生来矿区实习,就矿床的成因与在矿区工作的同志共同进行了探讨,取得了一致的看法,认为李坊重晶石矿床是受变质沉积矿床。矿床是沉积形成的,后期经过区域变质作用,使矿体的形态和矿石组构发生了变化。
Li square barite deposits found for more than 10 years, but proved to be large or large geological exploration team results of a geological survey. This discovery has aroused the attention of the Chinese and foreign geology circles and the mining industry, and has also put forward some different opinions on the genesis of the deposit in succession. Generally speaking, there are hydrothermal fluids, which are explained in layers and deposited. In 1981, the faculty and students of the Department of Geology and Mineral Resources of Fuzhou University came to practice in the mine and discussed the cause of the deposit together with the comrades working in the mining area. The consensus was reached that the Li Fang barite deposit was subject to metamorphic sedimentary deposits. Deposits are formed by sedimentation, and later metamorphism through the region, the ore body morphology and ore composition has changed.
