Geological phenomenon

Slaty cleavage: Slate unique continuous cleavage. It developed in the lower fine-grained metamorphic rock, the naked eye is extremely difficult to distinguish micro-cleavage domain or split stone; in the microscopic scale, the cleavage domain by the parallel arrangement of planar or interleaved layered like mica or chlorite silicate mineral-rich integrated thin-film or thin, width 0.005 mm; micro split stone composed of quartz, feldspar and other minerals, a collection of light-colored, shaped or lenticular sheet showed a width of 1 to 0.01 mm or less. Slaty cleavage makes the slate has good split of the flat rock split into very thin. mobile crusher for rent malaysia

Cleavage refraction: the strength of white rock, tough layer cleavages and cleavages weak layers intersect at different angles and bedding, tough layer of spaced cleavage, the larger angle with bedding; weak layer continuous cleavage, and bedding angle is smaller. Rectangular boudin: siliceous dolomite pull off a rectangular strip boudin, reflecting competent siliceous layer (hard layer) and high viscosity difference between the weak layer of dolomite. (Boudinage, you can still remember ~) rocks interbedded series of different mechanical properties of being vertical or near vertical rock formed by extrusion. Soft rock is pushed to the sides of the plastic flow, the folder in which the rock hard plastic deformation easily pulled off, the plane was constituted strip blocks were arranged in parallel, that is boudin. Pulled off the hard rock in the interval, or was wedged by the weak layer folds, or secreted by the deformation process of the filling material. how to operate stone crushing equipment

Lenticular boudin: limestone dolomite formation is relatively tough lenticular Boudinage. Both ends of the body’s secretion of sausage filling calcite, showing pressure solution exists. Flex: horizontal or flat rock, the rock suddenly becomes steep by the general exhibit the geniculate, due to bending or warping or other formations formed in moderate deformation. Geniculate fold: the early slaty cleavage wrinkled face was deformed, changing from left to right folding forms, both from the geniculate – gradual transition arc-shaped – box-shaped.

Asymmetric folds: refers to unequal wings fold axis in the plane and the plane is not perpendicular to each other, to the axial plane without wings marked face was wrinkled folds of mirror symmetry. For the continuous development of a series of asymmetric folds, if along the fold hinge plunging direction of observation, it can be folded surface morphology changes from long to short wing wing described as S or Z, they reflect the folds backward: S type is left-or counterclockwise backward; Z-type or clockwise for the right line backward. iron ore beneficiation plant

Parallel fold: fold geometry is a typical pattern. Composition of the fold as fold parallel curved surface, the thickness of the fold of the same layer remains constant, thickness, etc., it is called a fold; curved layers having the same center of curvature, so called concentric folds. Fold outwardly from the center plane of the radius of curvature is gradually increasing parallel to the fold, the curvature becomes smaller, more gentle rock; core portion in a direction towards the curvature becomes larger; parallel due to the corrugated layer of constant thickness and thus folds Form must be adjusted with depth. If anticline along its axis facing down, fold-plane bending increasingly closed, and even into the steeple anticline; or folds in order to adjust to the heart layer extrusion, there’s a small complex folds and thrust faults in the core; then down wrinkles disappear, a slippage occurs between the surface and the underlying rock. Generally developed in parallel folds of sedimentary strata is not bad, not too intense tectonic deformation occurs in the region.
