Dec 16, 2020 · Buenavista is a lava dome that formed at the northeasteast extreme of a propagating dyke system that extends 5 km east of Quilindaña peak. Between Quilindaña and Buenavista is another vent, Huahui, which emitted a 7 km long lava flow that flowed southeast to the caldera outlet carved out by the Chalupas river.
Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers ), [3] [4] often loosely cemented by calcium carbonate.
The most proximal (close to sediment source) and coarse grained of watertransported sedimentary environments is the alluvial fan. These cone shaped deposits form where high gradient narrow canyon streams disgorge onto flat plains at the mouths of canyons. At this point, streams typically lose the competence to transport framework clasts. Note, when applied to a .
The sand and stone flow into washing launder from feeding launder, rolls with the impellor, and grinds each other. The impurity covering the sand is washing away. At the same time, add more water, the strong water flow will take away waste and some lowweight wastes from washing launder. Through the above process, the washing function is finished.
