南盘江地区位于广西隆林县科峰,革步及贵州兴义、巴结一带,属南盘江中生代早期坳陷之西部。区内中三迭纪地层发育,相变规则而剧烈。安尼锡克期区内可分成三个相区,坝盘以北为碳酸盐台地边缘生物礁滩相。坝盘以南祥播、岩卡一线以北为台地边缘斜坡相。祥播、岩卡以南、巴结、革步一带为半深海浊积岩相,相带的划分明显受祥播——岩卡同生断裂控制。拉丁尼克期区内也划分为三个相区:箐口、泥凼一带以北为生物礁滩相;箐口以南、水打龙以北为碳酸盐台地边缘斜坡相;水打龙以南为浊积岩相。本文仅就浊积岩相特征进行讨论,生物礁相及斜坡相的特征将另文讨论。
Nanpanjiang region is located in Longfeng County, Guangxi Kefeng, progress and Xingyi, Guizhou, along the Badge, Nanpanjiang in the early Mesozoic Depression in the western. Three Triassic strata in the area development, the rules of phase change and intense. The Annihik area can be divided into three facies zones, and the north of the dam plate is the reef bank facies on the edge of the carbonate platform. Dam plate south sowing, rock card line north of the edge of the stage slope. Xiang sowing, south of rocky card, kapok, step by step for the semi-deep sea turbidite facies, the division of the phase belt obviously under the auspicious sowing - synoptic fracture control. The Latin-Nicol zone is also divided into three phase zones: Qiaokou and the north of Cotai are bio-reef-shoal facies; south of Qiaokou and north of Shui-long are carbonate facies slope facies; South Turbidity facies. In this paper, only turbidite facies characteristics are discussed, and the reef facies and slope facies characteristics will be discussed separately.
