1. Unknown_Error

2. From the picture, the first is quartz vein, quartz crystal is clearly visible. The second is felsic vein. The possibility of ore bearing in dikes is not great Some quartz veins occasionally contain minerals, such as gold, but they are invisible to the naked eye). Many minerals may not be visible with the naked eye even if they reach the instrial grade, so it is necessary to test and analyze them to determine whether they contain minerals.

Igneous rock formed by the condensation of magma ejected from the earth's surface, including various lavas and pyroclastic rocks. Intrusive rock refers to the rock formed by the magma in the asthenosphere drilling out and condensing in the depth of the crust when the pressure of the overlying strata is reced. The main differences in mineral composition are as follows:

1. Structurally,

intrusive rocks generally have equigranular whole crystalline and cryptocrystalline structures. Porphyry or porphyry like structures can be seen in the center of the rock mass, and the size is relatively uniform, while extrusive rocks condense rapidly, and the size of porphyry is relatively unstable

The intrusive rocks are generally massive structures, and there is no almond structure. The extrusive rocks are mainly composed of pores, almonds and rhyolitic structures. Finally, the content of dark minerals in the phenocrysts of extrusive rocks is generally less than that of intrusive rocks

The occurrence of intrusive rocks is often in the form of stock, dyke and dyke, and the contact of surrounding rocks has obvious metamorphic circle or contact metamorphic circle. The extrusive rocks can occur in layers, and there is no metamorphic circle in the surrounding rocks
