explosive breccia
解釋
爆發角礫巖-
Based on the derivation of metallogenic matters, mineralization and wallrock conditions, the gold deposits are subdivided into three main types : volcanic thermal type, subvolcanic rock - shallow to ultra - shallow porphyry thermal type, and concealed explosive breccia type of gold deposits
根據其金礦成礦物質來源、成礦作用及產出的圍巖條件可劃分為火山熱液型、次火山淺成斑巖熱液型和隱爆角礫巖型金礦床。 -
Abstract : to the principle and project that tu guangazhi proposed in 1990, the gold ore deposits in qinling ( shaanxi ) may be classified into fouowing types : archean high - grade gneiss type, fine grained fragmental rock - carbonate rock - silicilith type, metamorphic fragmental rock type, volcanic rock type, explosive breccia type, intrusive rock exo - and endo - contact zone type. inthis paper, the geological characteristics, metallogenic geological setting, the source of ore - forming materials, digenic mechanism and metallogenetic epoch of gold ore deposits are also discussed
文摘:參照塗光熾先生（ 1990 ）提出的礦床類型劃分原則與金礦分類方案，將陜西秦嶺地區原生金礦劃分為太古界綠巖建造型、細碎屑巖-碳酸鹽巖-硅質巖建造型、變質碎屑巖型、火山巖建造型、隱爆角礫巖型和侵入巖內外接觸型金礦，並對各類型金礦的地質特徵、成礦地質背景、成礦物質來源、礦床形成機制及形成時代等問題進行了論述和討論。 -
The hydrothermal breccia and karst in the beiya area are divided into 4 types and zones, including : sedimentary tuff and breccia induced by hydrothermal explosion and sedimentation on land surface ; hydrothermal sedimentary conglomerate and gas - explosive ejecting breccia related to sedimentation in and collapsing of some shallow karst caves ; netted hydotherma1 limcstone breccia and hydrothermal explosive breccia pipe related to hydrofracturing, corrosion and explosion in the hydrothermal channels ; and yellow granular limestone formed by simmering and alteration in the deep heated water reservoir
北衙地區熱水角礫巖和熱水巖溶可分為4種類型和層次，即地表相爆發沉積作用形成的沉積凝灰角礫巖、熱水沉積鮞狀灰巖與鈣華膠結角礫巖；與近地表洞穴沉積和垮塌作用有關的熱水沉積礫巖和汽爆射流角礫巖；與熱水通道相蝕裂和爆破角礫化作用有關的網路狀灰巖角礫巖筒和熱水隱爆角礫巖筒；深部相熱水浸煮蝕變灰巖。
