Laboratory-based mineralogical investigations involved examination of thin- and particulate sections for the heavy mineral contents and sedimentary textures.
These mineralogical changes take place over a section less than 300 m thick, and potentially indicate significant differences in transport distances and in provenance.
Other theories - proteins/ nucleic acids first and mineralogical origins - are also discussed in the context of information theory.
Alongside this, it proposes collecting geological and mineralogical data in o order to draw up a geological map of the region.
The rocks show pure magmatic fabrics and mineralogical assemblages, except at the contact with the high-grade metamorphic rocks.
The mineralogical and textural difference of the two iron oxides might reflect differences in the environment of precipitation.
It is concluded from mineralogical and chemical evidence that even smallscale crystallization and settling within a magma body puts its clear signature on the compositions.
Furthermore, mineralogical and biological evidence, along with molecular, biometric and particularly morphological data, must support a biogenic origin.
