The main achievements obtained in this paper are as follows : 1. some of new recognitions were obtained on such aspects as strata sequence, rock type, metamorphism, hydrothermal alteration and the sedimentary environment by the study on many profiles in this area, with discovery of volcanic rocks for the first time in ore - bearing strata and ore bodies
取的了如下主要成果和認識： 1 、通過對礦區地層多條剖面的研究，對地層的層序、巖石類型、變質作用、熱液蝕變及原巖沉積環境有了新的認識，特別是在賦礦地層及礦體中首次發現了火山巖。To make the yanshanian volcanic tempral and spatial distribution and evolution law clear, study the relationship of the deep crust - mantle processes and the volcanic rocks, the author selects the typical areas, xishan of beijing, duolun of inner mongolia, west liaoning, as the study areas where the volcanic rocks strata are developed. through the emphasised geological profiles of yanshanian volcanic strata being surveyed, much field work being done detailly, the small volcanic eruptive units have been defined originally, the levels of volcanic activity rhythm being constructed gradually, as a result, a integrated and systemic rhythm of yanshanian volcanic acivity has been constructed
為了揭示該區燕山期火山巖火山活動的時空分佈與演化特徵，探討與深部殼幔過程的關系，選擇了燕山期火山巖地層發育比典型的北京西山、內蒙多倫、冀北和部分遼西等地區，系統的測制了燕山期火山巖重點地層剖面，通過野外大量的詳細觀察，從建立最小的火山噴發單元開始，逐步地建立火山活動節律的級別，結合區域地層對比，建立了一個比較完整的燕山期火山活動節律及其級序。According to distribution regularity of elements in strata, intrusive rocks, ores and orebodies of the zhongqiuyang volcanogene hydrothermal copper deposit, this paper has elucidated characteristics of geochemical primary anomalies, determined indicator elements related to the ore deposit and their sequence of zoning, established indices for evaluating denudation extent of ore deposit, and formulated geochemical anomaly pattern of the ore deposit
摘要據鐘丘洋火山熱液型銅礦床的地層、侵入巖、礦石和礦體中元素的分佈規律，闡明了該礦床的地球化學原生異常特徵；確定了與礦床有關的指示元素及其分帶序列；建立了礦床剝蝕程度的評價指標及該礦床的地球化學異常模式。
