根据西准噶尔玛依塔巴克一带区域地质调查最新成果,对《新疆岩石地层》中中晚石炭世哈拉阿拉特组重新进行厘定,建立哈拉阿拉特组副层型剖面,修正了原哈拉阿拉特组正层型剖面的地层层序,将原正层型剖面1~6层归早石炭世包古图组,将王玉净等划归下二叠统佳木河组的大套火山岩—火山碎屑岩组合置于哈拉阿拉特组下部。厘定后的哈拉阿拉特组分为7个岩性段,时代为晚石炭世。重新厘定后的本组,正确反映了其层序、岩石组合和地层学属性,为本区石炭系研究提供了准确完整的层序和对比剖面。
According to the latest results of the regional geological survey in the Mayta Tabak area, west Junggar, the Middle-Late-Carboniferous Hala’alat Formation in the “Xinjiang Rock Strata” was re-determined and the sub-layer profile of the Hala’alat Formation was established. The original Hara Stratigraphic sequence of the Ordovician positive stratigraphic section is that the 1st to 6th strata of the former normal stratigraphic are governed by the Early Carboniferous Paleo-Tupa Formation and the Wang Yu-jing et al. Are assigned to the large set of volcanic rocks of the Permian Jiamuhe Formation - volcanoes The clastic assemblages are placed in the lower part of the Hala’alat Formation. The determined Hala’alat component is composed of seven lithologic segments, dating from Late Carboniferous. This group after re-determination correctly reflects its sequence, rock assemblage and stratigraphic properties, providing an accurate and complete sequence and comparative profile for the Carboniferous research in this area.
