摘要: 冀西北髫髻山组火山—沉积地层发育, 但生物化石匮乏, 前人同位素测年资料不足且测年方法陈旧, 致使其形成时代一直存在争议。为了准确确定该组地层的形成时代, 研究其形成的区域大地构造背景, 笔者对宣化盆地髫髻山组的岩性组合开展了详细的野外调查, 对地层上部粗面质火山岩开展了岩石学、岩石地球化学及高精度同位素测年研究, 获得了161.1±1.2 Ma和162.5±1.3 Ma的LA-ICP-MS锆石U-Pb同位素年龄; 岩石学、岩石地球化学特征表明, 上部粗面质火山岩为钾玄岩系列, 岩石具有轻稀土元素富集, Rb、K、Th、Ce、Zr、Hf等元素相对富集, Ba、Nb、Sr、P、Ti相对亏损的特征; 通过主要参数对比和图解判别, 确定岩浆主要源于大陆地壳物质熔融, 粗面质火山岩形成于挤压大陆边缘火山弧构造背景。综合研究认为, 髫髻山组主要形成于中侏罗世, 并延续至晚侏罗世, 其上部粗面质火山岩形成于板内挤压构造背景, 该成果对中生代火山岩—沉积地层划分对比及形成环境研究补充了新资料。Abstract: The Tiaojishan Formation in northwestern Hebei Province is home to volcanic-sedimentary strata. Due to the lack of fossil organisms, insufficient isotopic dating data, and outdated dating methods, the formation epochs of these strata have been controversial. To accurately determine their formation epochs and examine their regional geotectonic setting, this study conducted a detailed field investigation of the lithologic assemblage of the Tiaojishan Formation in the Xuanhua Basin. Petrological, petrogeochemical, and high-precision isotopic dating studies were conducted on the trachytic volcanic rocks in the upper segment of the formation, obtaining the LA-ICP-MS-based zircon U-Pb isotopic ages, which were 161.1±1.2 Ma and 162.5±1.3Ma. As indicated by the petrological and petrogeochemical characteristics, these trachytic volcanic rocks belong to the shoshonite series, exhibiting enriched light rare earth elements, relatively enriched elements including Rb, K, Th, Ce, Zr, and Hf, and relatively depleted Ba, Nb, Sr, P, and Ti. According to the comparison of principal parameters and graphical discrimination, the magma originated primarily from the melting of continental crustal materials and formed in the tectonic setting of compressional continental margin volcanic arcs. The comprehensive research reveals that the Tiaojishan Formation formed primarily during the Middle Jurassic and continued to the Late Jurassic, and the trachytic volcanic rocks in its upper segment formed in the intraplate compressional tectonic setting. The results of this study provide new data for the division and correlation of Mesozoic volcanic-sedimentary strata and the analysis of their formation environment.
