Foliated grade
If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.Google radiometric dating.
Phyllite is a foliated metamorphic rock that is texturally intermediate between slate and schist. It exhibits a greater degree of metamorphism than slate but not as much as schist, resulting in a medium-grain texture with a glossy sheen.
A baked margin refers to a financial margin requirement that a trader must fulfill by depositing additional funds into their account to cover potential losses on open positions. The margin is "baked in" to the system to ensure that traders have enough funds to honor their obligations.
Schist is a medium-hard metamorphic rock that forms from the alteration of other rocks under high temperatures and pressures. It can range in hardness depending on the minerals present, but generally falls between 2.5 to 4 on the Mohs scale of hardness.
A sedimentary rock can change from that to a metamorphic rock then into an Igneous rock. e.g. Mudstone (sedimentary) is in the Zone of Diagenesis, when it is subjected to regional metamorphism (in mountain belts) it changes from a mudstone to a slate (low grade) then to a Phillite (medium grade) then a Schist (medium) then a gneiss (high grade) then into a Milonite (high grade) then once past the line of partial melting it has so much pressure and so much temperature that it turns into an Igneos rock. This is the basic explanation of this. If you want to know more, just ask me.Sedimentary rocks are changed into metamorphic by being buried deep enough that the heat and pressure alter their text, mineralogy, or other characteristics.
really
go f*ck yourselfs!...
Peat (not much of a rock).
Metamorphic
Very(much), vary(differs)
Usually it is sedimentary rock that is changed into metamorphic - however it is entirely possible for igneous rock to become metamorphic as well. Metamorphic means different form, and in the geological since it mean rock that has been changed by heat and pressure. Now there isn't too much that can be done to igneous rock to change it chemically, by heat and pressure. But it can undergo physical distortions.
Differs on the cash refund.
Postage differs depending on where you live.
50% from each parent.
Not that much, about 5%. You could check other textbooks though.
it differs on what card it is and the condition
The starting wage for all employees in the United States is $7.25, how much they make in a year differs as hours differ. But there is your salaried managers which their salary differs from store to store.
