Geology: How does the Earth's mantle melt?
The Earth’s Upper mantle consists of ultramafic rocks. Their main components are olivine and orthopyroxene, as well as clinopyroxene and an Al-phase . Additionally mantle rocks can contain phlogopite, amphibole or carbonate. From these different compositions different mantle melts can be produced, depending on the temperature and pressure conditions. But how can you even melt a mantle rock? First we need to understand the position of the solidus and the liquidus in peridotites during mantle conditions as well as the realistic path of the that could cross the solidus. The difference between the liquidus and the solidus in dry peridotites is roughly 800 °C. At higher pressures of...
Ecology: 10# STEEMIT-EDUCATION OF ECOLOGY [Plant interaction with soil]
This week I am doing a research on the plants, in this research I will analyze the relationship between the plant with the soil, on this occasion I do a relationship analysis of the soil with soil using beans commodity.
