赣中碰撞混杂岩带

毛集—二郎坪断陷带中的主体构造格架是复式倒转褶皱系。中央是朱庄（河前庄）—板山坪—太平镇主背斜带，南、北两侧各有两个倒转向斜构造。南侧为大庙—青山倒转向斜和张家大庄倒转向斜；北侧为石灰窑倒转向斜和彭老家倒转向斜。这一复式倒转褶皱系的发现及确立，对断陷带中二郎坪群及其相关地层的划分对比和海相火山岩型金、银、铁、铜、硫等矿产勘查工作具有重要意义

CENTRAL JIANGXI COLLISION MELANGE ZONE

The main structural framework of the Maoji Erlangping down faulted zone in Henan is represented by a composite overturned fold system.Its center is the Zhuzhuang (Heqianzhuang) Banshanping Taipingzhen principal anticline belt, flanked by overturned synclines on the north and south sides, i.e., the Damiao Qingshan overturned syncline and Zhangjiadazhuang overturned syncline on the south and the Shihuiyao overturned syncline and Penglaojia overturned syncline on the north. The discovery and establishment of this composite overturned fold system are of great significance for the stratigraphic division and correlation of the Erlangping Group and its related strata in the down faulted zone and exploration of marine volcanic type mineral deposits such as gold, silver, copper and sulfur deposits.
