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 employer must notify the health plan within 30 days if you lose or quit your job, die or become entitled to Medicare. You must notify the plan, generally within 60 days, if the reason for COBRA eligibility is because of divorce, legal separation or losing dependent status as a child. The health plan then has 14 days to respond with information about how to elect COBRA, and you and your family have 60 days to decide. Not all of you have to elect COBRA. Even if you waived the option, for instance, your spouse and kids could still elect COBRA, or vice versa.
