| 摘 要： | 南坑石膏矿床位于赣中南泰和县吉泰盆地,是目前在赣中南早禾凹陷中发现的唯一石膏矿床.层状含膏层赋存於上白垩统周田组中.按其分布分为东、西二个矿段,东矿段（8-22线）和西矿段（7-0线）,矿化总面积为29 km^2.初步分析表明,矿床严格受地层、构造古地理环境、古气候等因素控制.以往对矿床地质评价工作程度较低,今后需重新评价,以扩大矿床规模.矿区外围的泰和凹陷、早禾凹陷和桐坪凹陷,成矿地质条件与南坑石膏矿床类似,而且在泰和凹陷已发现石膏矿层,是外围找矿最有利的远景区.

| Abstract: | Nankeng Gypsum Deposit is located at Jitai basin,Taihe county area in south Jiangxi,which is the unique one found in Zaohe depression.Bedded gypsisum occurred in the Late Cretaceous Zhoutian Group.Based on geographic distribution,this deposit is divided into two ore levels,East(Line 8-22) and West(Line 7-0) ore levels,covering a total mineralized area of 29 km~2.A preliminary analysis has revealed that the deposit is strictly controlled by strata,structural paleogeography,and paleoclimate.The ore has great potential,so geological evaluation will be made for outline the ore deposit.In the immediate vicinity of the deposit the geological ore-forming conditions of Taihe,Zaohe and Tongping depressions are consistent with that of Nankeng.Gypsum mineralization has even found in Taihe depression,therefore it is the most favorable target area for searching ore. |
