Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means change in form. The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 Â°C) and pressure (1500 bars), causing profound physical and/or chemical change.extures are separated into foliated and non-foliated categories. Foliated rock is a product of differential stress that deforms the rock in one plane, sometimes creating a plane of cleavage. For example, slate is a foliated metamorphic rock, originating from shale.
Thereâs no time limit for how long the period of consultation should be, but the minimum is: 1  20 to 99 redundancies-the consultation must start at least 30 days before any dismissals take effect. 2  100 or more redundancies-the consultation must start at least 45 days before any dismissals take effect.
The annual ADR Limit will be divided by eight to establish the ADR cycle limit which is the maximum number of claims that can be included in a single 45-day period. Recovery Audit Auditors may go more than 45 days between record requests but in no case shall they make requests more frequently than every 45 days.
