porphyroblast मीनिंग इन हिंदी

उदाहरण वाक्य

1. The augen grows by crystallisation of a " mantle " of new mineral around the porphyroblast.
2. Whereas most researchers are convinced that porphyroblast may rotate during deformation, some believe that porphyroblasts do not rotate.
3. The core of the augen is a porphyroblast or porphyroclast of a hard, resilient mineral such as garnet.
4. This concentrated impurity deposit forms a re-entrant as it is absorbed by the growth of the andalusite porphyroblast.
5. The timing of porphyroblast growth can be determined by examining the microstructure preserved ( or not ) within them as poikiloblasts.
6. A "'poikiloblast "'is a porphyroblast mineral with small inclusions of the previous rock in it.
7. The relationship of porphyroblast growth to deformation is typically evaluated by comparing the shape orientation of trails of mineral inclusions in the porphyroblast to the matrix fabric.
8. The relationship of porphyroblast growth to deformation is typically evaluated by comparing the shape orientation of trails of mineral inclusions in the porphyroblast to the matrix fabric.
9. This may be possible by observing porphyroblast formation in cleavages of known deformation age, by identifying metamorphic mineral assemblages created by different events, or via geochronology.
10. As porphyroblasts grow, the foliation may be preserved as oriented inclusions trapped by the porphyroblast as it overgrows them, and this is helpful for tracking changing deformation planes.
