paragenetic

Further paragenetic minerals are alabandine, enstatite, graphite, plagioclase and schreibersite.

The paragenetic sequence in mineral formation is an important concept in deciphering the detailed geologic history of ore deposits and metamorphic events.

Violarite is also reported to be produced in low-temperature metamorphism of primary sulfides, though this is an unusual paragenetic indicator for the mineral.

The crust that had covered the thing was not a random accumulation of interstellar dust, as they had first surmised, but a sort of callus composed of local materials coupled with the Moyani vessel's own paragenetic material.

It is characterized by the existence of two fóssil paragenetic main conduits of about one decametre in diameter with dendritic tributaries, and a set of semi-active passages in a dendritic pattern at the north and angulate at the south.

A sediment may exhibit one or more phases of any, or all, of these processes; the task of the sedimentary petrographer is to unravel the different events, place these in a paragenetic sequence and then build on these in interpreting the burial history of the sediment.

The first one is represented by superficial phreatic galeries of small diameter, the second one by the Galeria Gémea paragenetic main conduit, the third one by the Galeria Grande and his tributaries and the last one by the active and semi-active galeries of the lower cave levels.
