根據不同構造層中變形方向及後期構造疊加的分析，對本區的構造應力場及變形場進行了探討，本區蓋層早期階段（ d - c ）為近南北向的伸展拉張，二疊紀（特別是晚二疊世）的伸展方向可能發生了改變，除在各斷裂帶繼承性活動外，沿南北方向又新生了一些半地塹。而在擠壓變形時，印支期主要為近南北向擠壓，燕山早期為nw - se向擠壓，燕山晚期為nne - ssw向擠壓，而喜山運動可能經歷了從ew向向sn向方向擠壓的轉變。Detailed studies of tectonic unit and mineralized pedigree in each tectonic unit and each period provided that tectonic evolution passed an evolutionary sequence from early extension - transition - late compression that correspond to mineralization - sediment and submarine eruption - exhalation mineralization - moderate to acid magma and tectonic hydrothermalism that are relevant to mantle - derived magma and volcanic activities ; the mineralized pedigree can be indicated as mantle derived - inner basin and deep source - crust source ore - forming materials
