WebNotes: The number of cleavage planes can differ from mineral to mineral. Mica (e.g. biotite, chlorite or muscovite) has one cleavage plane, feldspar (e.g. orthoclase or plagioclase) has two which intersect at 90°, and amphibole (e.g. hornblende) has two which do not intersect at 90°. Calcite has three cleavage planes which do not intersect at ...
WebApr 25, 2024 · Feldspar usually dissolves partially along cleavage planes and fractures, resulting in the formation of numerous secondary intragranular pores (Figure 6h). In the regions with strong dissolution, the secondary intergranular and intragranular pores are widely developed, and the porosity is high. threadfix file formatWebAll alkali feldspars show two cleavage planes intersecting close to 90° on sections parallel to the c axis. Euhedral crystals are prismatic or tabular, with elongated prismatic sections and rectangular to square-like basal sections.
