化學組成, 鍵及結構:輝石和基性長石

綠岩，又名福建青、大湖青、青石，成分相當於輝長岩的淺成岩。顯晶質,細-中粒，暗灰-灰黑色,常具輝綠結構或次輝綠結構。深灰、灰黑色。主要由輝石和基性長石（與輝長岩成分相當的淺成岩類）組成，含少量橄欖石、黑雲母、石英、磷灰石、磁鐵礦、鈦鐵礦等。

Chemical composition, bonding and structure: Pyroxene and mafic feldspar

Greenstone, also known as Fujian Green, Green Lakes, bluestone, composition equivalent gabbro shallow diagenesis. Significant crystal, fine – medium grained, dark gray – gray and black, often with diabase diabase structure or sub-structure. Dark gray, gray and black. Mainly by pyroxene and mafic feldspar (and gabbro composition fairly shallow diagenetic class) composition, containing a small amount of olivine, biotite, quartz, apatite, magnetite, ilmenite and so on.

原生物：(化石)

輝綠岩爲深源玄武質岩漿向地殼淺部侵入結晶形成，常呈岩脈、岩牆、岩床或充填於玄武岩火山口中，呈岩株狀產出。但輝綠岩也常常在造山帶單獨出現。

Living Specimens: (Fossil)

diabase for deep basaltic magma intrusion to the shallow crust crystal formation, often dykes, dykes, sills or filled crater in basalt, rock strains was like output. But diabase often appear alone in orogenic belts.

輝綠岩成分相當於輝長岩的基性淺成岩。顯晶質,細-中粒，暗灰-灰黑色,常具輝綠結構或次輝綠結構。輝綠結構指輝石的平均粒徑大於斜長石平均長度，呈現一顆輝石包裹許多斜長石的現象；如果輝石平均粒徑小於或近似於斜長石平均長度，則呈現輝石局部地包裹斜長石或與斜長石相間，稱爲次輝綠結構。對於輝綠結構和次輝綠結構的成因的說法不一，一般認爲是由於淺成條件下礦物結晶顺序的早晚所形成。含較多填隙石英，或含由石英和正長石構成的填隙文象狀交生體的輝綠岩，稱石英輝綠岩，或拉斑輝綠岩；含沸石、正長石、霓輝石或霓石的，稱鹼性輝綠岩。易變輝石和紫蘇輝石可以出現於石英輝綠岩中，橄欖石則可出現於鹼性輝綠岩中。輝綠岩常呈岩床、岩牆、岩脈和岩席，也呈岩頸或岩株充填於玄武岩火山口中，輝綠岩的上述產狀，是它區别於輝長岩和玄武岩的主要標志。大規模的輝綠岩侵入體，如眾多的輝綠岩岩床或厚300～400米的輝綠岩板狀地質體，往往出現於上覆蓋層爲中等厚度（約2000～3000米）的條件下，其原因是岩漿易於顺層或沿裂隙貫入。 。

Gabbro diabase component corresponds to the base of the shallow diagenetic. Significant crystal, fine – medium grained, dark gray – gray and black, often with diabase diabase structure or sub-structure. Diabase structure refers to the average particle size of pyroxene is greater than plagioclase average length, showing a pyroxene wrapped many plagioclase phenomenon; If pyroxene average particle size of less than or similar to plagioclase average length, showing pyroxene partially wrapped plagioclase or plagioclase and white, called sub​​-hui green structure. The causes of diabase diabase structure and sub-structure vary, generally thought to be due to a condition sooner or later, shallow mineral crystals formed by the order. Containing more interstitial quartz, or text object containing interstitial cross-shaped living body composed of quartz and diabase are composed of feldspar, quartz called diabase, or tholeiitic diabase; containing zeolite, feldspar, pyroxene, or Ni aegirine, called alkaline diabase. Variable pyroxene and pyroxene basil can occur in quartz diabase, the olivine diabase may occur in alkaline. Changcheng diabase sills, dykes, dykes and rock seats, also showed a rock or rock neck strain filled crater in basalt, diabase above occurrence, is it different from the main symbol of gabbro and basalt. Under the massive diabase intrusions, such as the numerous diabase sills or 300 to 400 m thick diabase tabular geologic body, often appear on the cover layer of medium thickness (about 2000 to 3000 m) conditions the reason is easy to shun the magma layer or along fissures penetration.
