摘要

摘要: 研究目的
鹤岗盆地是黑龙江东部白垩纪盆地群的重要组成部分，对其进行沉积充填特征和源区物质组成方面的分析，可有效揭示黑龙江东部白垩纪盆山系统演化和构造古地貌变迁的重要信息。
研究方法
针对鹤岗盆地关键层位开展了碎屑锆石年代学研究，在充分参考已有研究成果的基础上，系统梳理了黑龙江东部白垩纪地层的年代学格架。
研究结果
结果表明，下白垩统城子河组、穆棱组和东山组分别形成于116~111 Ma、111~107 Ma和107~105 Ma，上白垩统猴石沟组底界年龄接近104 Ma。根据碎屑锆石年龄组成，认为黑龙江东部白垩纪盆地群在城子河组与穆棱组时期已经相互贯通，形成了统一的、面积广阔的“大三江盆地”原型。此时的古地貌为西高东低，小兴安岭成为盆地主要的母岩源区。至猴石沟组时期，佳木斯地体发生差异隆升，“大三江盆地”原型逐渐解体，西侧的小兴安岭被淹没至水下，古地貌由西高东低过渡为东高西低。
结论
猴石沟组下伏的角度不整合与此次盆山系统调整密切相关，其对应的时间跨度可能仅有1 Ma，甚至更短。

Abstract: Objective
Hegang Basin is an important component of the Cretaceous basin group in eastern Heilongjiang. The analysis of its sedimentary filling characteristics and provenance composition can effectively reveal key information about the evolution of the Cretaceous basin−mountain system and the transformation of tectonic paleogeomorphology in eastern Heilongjiang.
Methods
To well constrain the chronological framework of the basin fill, detrital zircon U−Pb dating for the crucial formations has been conducted.
Results
Based on compiling the published and our own data, ages for the Lower Cretaceous Chengzihe, Muling, and Dongshan formations are assigned to be 116~111 Ma, 111~107 Ma and 107~105 Ma, respectively, and the lower age limit for the Upper Cretaceous Houshigou Formation is thought to be ca. 104 Ma. The characteristics of detrital zircon age distribution reveal that the Cretaceous basin groups have already connected and unified a much larger prototype basin, namely the “Great Sanjiang Basin”, during the deposition of the Chengzihe and Muling formations. At that time, the paleogeography featured by a high elevation in the west and a low elevation in the east, and the Lesser Xing’an Range became the main source area for the unified basin. By the deposition of the Houshigou Formation, regional tectonic regime turned to be contraction from extension, resulting in differently uplift in the Jiamusi block and destruction of the “Great Sanjiang Basin”. Under effects of erosion and thrusting load from the eastern continental margin, the Lesser Xing’an Range reduced markedly in the elevation and eventually submerged by the water.
Conclusions
The regional unconformity under the Houshigou Formation has a tightly relationship with this basin−mountain system adjustment, and its corresponding time span could be less than 1 million years.
