VOLCANIC AND INTRUSIVE ROCKS

TECTONIC EVOLUTION

➢Mainly filled by Paleozoic rocks, which reaches thicknesses of more than 5,000m.

➢ Three Paleozoic Supersequences from bottom to the top:

i. Ordovician-Devonian;

ii. Devonian-Carboniferous;

iii. Permian-Carboniferous (which hosts the Potash Mineralization in evaporite sequence of Nova Olinda Fm)

➢One Mesozoic-Cenozoic Supersequence.

EVAPORITE SEQUENCE OF AMAZON AND SOLIMÕES BASINS

LATE CARBONIFEROUS – 300 Ma EARLY PERMIAN – 280 Ma

➢Evaporite sequence: Deposited in a relatively stable tectonic period during the Permo-Carboniferous (Szatmari et al. 1975).

➢Probably developed in dry conditions and in an intracontinental basin partially isolatedfrom Panthalassa Ocean by Hercynian Ridges.

ICP-OES vs. PXRF:• Results generally have a good correlation.

• High precision and low accuracy.

• Influenced by the KCl content of theinterval, as in any semi-quantitativeanalysis

• Different correlation factors between lowand high KCl grades.
