本文以程裕淇教授等地质学家提出的矿床成矿系列理论为指导，对河北主要成矿区带与岩浆作用有关的矿床成矿系列进行了划分。共划分出１０个矿床成矿系列，１２个亚系列，３８个矿床式。河北跨华北地台与内蒙—大兴安岭褶皱系两个一级大地构造单元，由燕山台褶带、内蒙地轴、山西断隆等５个二级构造单元组成。区域地质经历了活动（Ａｒ－Ｐｔ１）、稳定（Ｐｔ２－Ｐｚ２）、活化（Ｍｚ－Ｋ１）三大发展阶段，经多旋回的构造岩浆活动，形成华北地台北缘中段和兴安—太行南段两个主要成矿区带。华北地台北缘中段成矿带是纬向成矿带，基本上受燕山台褶带控制。经历了奠基（Ａｒ－Ｐｔ１）→雏型（Ｐｔ２）→基本形成（Ｐｚ２）→成型（Ｍｚ）的发展过程，形成了以有色、贵金属及黑色矿产为主的第Ⅰ，Ⅲ，Ⅳ，Ⅴ，Ⅸ－１，２等５个矿床成矿（亚）系列，６个亚系列、１９个矿床式。兴安—太行南段成矿带是中生代ＮＮＥ向成矿带，经印支、燕山旋回形成。成矿带基本上受太行山深断裂带控制，不受大地构造单元限制。北段与华北地台北缘中段成矿带交接叠覆。本成矿带经历了奠基（Ａｒ－Ｐｔ１）→雏形（Ｔ）→成型（Ｊ－Ｋ）的发展过程，形成了以黑色、有色、贵金属及放射性矿产为主的第Ⅱ，Ⅳ，Ⅶ，Ⅷ，Ⅸ－
In this paper, Professor Cheng Yuqi and other geologists proposed mineralization series theory as a guide, the main metallogenic belt in Hebei and magmatic ore-forming series related to the division. A total of 10 mineralization series of deposits, 12 sub-series, 38 types of deposits. There are two first-grade geotectonic units between Hebei across North China and the Inner Mongolia-Daxinganling fold system. They are composed of five second-level tectonic units, such as the Yanshantai fold, the Inner Mongolia axis and the Shanxi fault. The regional geology experienced three major stages of activity (Ar-Pt1), stability (Pt2-Pz2) and activation (Mz-K1). After the multi-cycle tectonic magmatism, the middle part of the northern margin of North China and the southern part of Xing’an-Taihang A major metallogenic belt. The middle part of the northern margin of the North China Platform is a zonal metallogenic belt that is basically controlled by the Yanshan platform fold belt. Experienced the development process of Ar-Pt1 → Pt2 → Pz2 → Mz, forming the first, the third, the fourth, the fifth, the fifth, the fifth, Ⅸ-1,2 and other five mineral deposits (sub) series, six sub-series, 19 deposits. The Xingan-Taihang southern segment metallogenic belt is a Mesozoic NNE-metallogenic belt formed through the Indo-China and Yanshanian cycles. The metallogenic belt is basically controlled by the deep fault zone in the Taihang Mountains and is not restricted by the tectonic unit. North section and North China platform in the northern margin of the transitional metallogenic belt overlaps. The metallogenic belt has undergone the process of Ar-Pt1 → T → J-K formation, forming Ⅱ, Ⅳ, Ⅶ, Ⅷ with black, colored, precious metal and radioactive minerals , Ⅸ-
