उदाहरण वाक्य
- Pyroclastic volcanic plateaus are produced by massive pyroclastic flows and they are underlain by pyroclastic rocks : agglomerates, tephra, volcanic ashes cemented into tuffs, mafic or felsic.
- The lava flows are more viscous, and therefore shorter and thicker, than the corresponding Hawaiian eruptions; it may or may not be accompanied by production of pyroclastic rock.
- Cockercombe tuff is a greenish-grey, hard pyroclastic rock formed by the compression of volcanic ash and is found almost exclusively in the south-eastern end of the Quantock Hills.
- Most of this detritus is erosional in nature, but pyroclastic rocks created by hot avalanches of extruded lava also contribute . thick olivine basalt found in the Jaz Murian depression may also come from Bazman.
- These include broad and shallow craters with diameters of with pyroclastic rocks, cryptodomes with diameters of up to and heights of, scoria cones reaching a height of with lava flow fields and individual lava flows.
