Slate was formed under low-grade metamorphic conditions—i.e., under relatively low temperature and pressure. The original material was a fine clay, sometimes with sand or volcanic dust, usually in the form of a sedimentary rock (e.g., a mudstone or shale). The parent rock may be only ...
(parent-daughter) decoupling was discovered [34]. Our powdered separates ranged from 11 to 35 milligrams. Arguments for a minimum sample size have been advocated [36], but it has also been shown that even sub-mm molybdenite samples can be dated, provided the “rock container” surrounding ...
