摘要
灯塔海积石膏矿床赋存于下寒武统馒头组—碱厂组中。７０年代在本区进行地质勘查时发现了馒头组Ⅰ号石膏矿（层），近年在找矿工作中所获得的重大突破是在碱厂组中发现和评价了新的膏层（Ⅴ号石膏工业矿层），Ⅴ号膏层厚度大、品位高、质量纯，且储量可观。这一发现为今后寻找和评价新的石膏层位，研究其地质特征、规模、矿石类型，以及矿床分带规律、成因与找矿标志提供了依据。
Dengta marine built gypsum deposits occurred in Mantou Jianchang Formations,Lower Cambrian. In 1970's,a gypsum ore bed was discovered in Mantou F.,which named I gypsum ore bed; In recent years, another gypsum ore bed was discovered in Jianchang F.,which named Ⅴ gypsum ore bed. Ⅴ gypsum ore bed had been valued to be large in thichness, high in grade, pure in quality and impressive inreserves. The paper introduce the types and quality of ores,the geological characteristics, scale, zoning regular,genesis and prospecting criteria of the gypsum deposits.
