文介绍在上杭县庐丰发现的两个中石炭统剖面，并划分为林地组和黄龙组两部份．林地组为陆相碎屑岩，厚度３４４—３６９米，中上段以植物化石 Ｒｈｏｄｅｏｐｔｅｒｉｄｉｕｍ ｃｈｉｎｇｈａｉｅｎｓｅ—Ｎｅｕｒｏｐ－ ｔｅｒｉｓ ｇｉｇａｎｔｅａ组合为特征．据此，我们提出林地组的主体应属于纳缪尔期的新见解．黄龙组以白 云质灰岩和晶质灰岩为主，底部为铁泥质凝灰质角砾岩及碎裂硅质岩，或相变成铁矿层（马坑式铁矿 的主矿体），厚度７５米．含两个蜒类化石带，即下部的Ｐｒｏｆｕｓｕｌｉｎｅｌｌａ带及上部的 Ｆｕｓｕｌｉｎａ带， 时代为中石炭世晚期． 庐丰的中石炭统发育良好，层序完整，化石丰富，可作为福建省的典型剖面．
The text introduces two Middle Carboniferous sections found in Lufeng, Shanghang County, and is divided into two parts, the forest land group and the Huanglong group. The woodland group is continental clastic rocks, 344-369 meters in thickness, and the middle and upper strata are characterized by a combination of the fossil plant Rhodeopteridium chinghaiense-Neuropitis gigantea. Accordingly, we propose that the main body of the forest land group should belong to the new opinion of the Muir Wood. The Huanglong Formation is dominated by dolomitic limestone and crystalline limestone, with argillaceous tuffaceous breccia and fractured siliceous rock at the base or phase transformation into an iron ore deposit (the main ore body of the Makeng-type iron mine) , The thickness of 75 meters. There are two serpentinal fossils, the lower Profusulinella zone and the upper Fusulina zone, dating from the Late Carboniferous. The Carboniferous of Lufeng is well-developed, complete in sequence and rich in fossils, which can be used as a typical section in Fujian Province.
