新疆若羌县阿热力一带位于东昆仑西段北坡、柴达木盆地西南缘。地层区划隶属于秦祁昆地层区、东昆仑-中秦岭地层分区,该区冰沟群分布广泛。对该区开展区域地质调查、对冰沟群的沉积环境和层序地层进行分析研究具有重要地质意义。在开展区域地质调查中,采用路线调查、剖面测量、实验测试等方法对冰沟群的岩性特征、岩石组合、地球化学特征、古生物特征以及形成时代等进行了系统研究,依据岩石组合特征将其划分为狼牙山组和丘吉东沟组。把该区冰沟群与区域上都兰县冰沟群层型剖面进行了对比,通过对比研究,认为该区的冰沟群与都兰县冰沟群层型剖面具明显可对比性。依据岩性特征、岩石组合特征、古生物特征等,对冰沟群沉积环境进行了分析,认为狼牙山组沉积环境属于潮下较深水陆棚相低能环境;丘吉东沟组属于浅海陆棚相带内缘斜坡沉积环境。并对冰沟群层序地层进行了划分,将其划分为2个Ⅲ级层序,即第一层序（B-1）和第二层序（B-2）。
新疆若羌縣阿熱力一帶位于東昆崙西段北坡、柴達木盆地西南緣。地層區劃隸屬于秦祁昆地層區、東昆崙-中秦嶺地層分區,該區冰溝群分佈廣汎。對該區開展區域地質調查、對冰溝群的沉積環境和層序地層進行分析研究具有重要地質意義。在開展區域地質調查中,採用路線調查、剖麵測量、實驗測試等方法對冰溝群的巖性特徵、巖石組閤、地毬化學特徵、古生物特徵以及形成時代等進行瞭繫統研究,依據巖石組閤特徵將其劃分為狼牙山組和丘吉東溝組。把該區冰溝群與區域上都蘭縣冰溝群層型剖麵進行瞭對比,通過對比研究,認為該區的冰溝群與都蘭縣冰溝群層型剖麵具明顯可對比性。依據巖性特徵、巖石組閤特徵、古生物特徵等,對冰溝群沉積環境進行瞭分析,認為狼牙山組沉積環境屬于潮下較深水陸棚相低能環境;丘吉東溝組屬于淺海陸棚相帶內緣斜坡沉積環境。併對冰溝群層序地層進行瞭劃分,將其劃分為2箇Ⅲ級層序,即第一層序（B-1）和第二層序（B-2）。

Areli belt in Ruoqiang county in Xinjiang Uygur Autonomous Region is in north slop of west part of eastern Kunlun mountain and southwest edge of Chaidamu basin.Stratigraphic district belongs to Qinling-Qilianshan-Kunlunshan mountain area,eastern Kunlun mountain and middle Qinling stratigraphy layers.The Binggou group is widely distributed in this area.It has important geological significance for carrying out regional geological survey and analysis on depositional environment and sequence stratigraphy of Binggou group.In carrying out regional geological survey,by using the route survey,profile measurement and test method,lithology characteritics,rock compositions,geochemical characteristics,paleontological characteristics and formation age in Binggou group were investigated sysmetically.According to rock composition characteristics,it can be divided into Langyashan formation and Qiujidonggou formation.Stratotype sections of Binggou group in this area and in Dulan county have been compared.Through comparative study,it is regarded that stratotype sections of Binggou group in these two areas have obvious comparability.According to the lithology characteristics,characteristics of rock association and paleontology,sedimentary environment of Binggou group has been analyzed.It is regarded that the sedimentary environment of Langyashan formation belongs to deep water shelf phase low energy environment under tide;while Qiujidonggou formation belongs to shallow marine shelf facies sedimentary environment of the inner slope.The Binggou group sequence stratigraphy is divided into 2 grade Ⅲ sequences,that is the first succession（B-1） and second（B-2） succession.
