830-Million-Year-Old Microorganisms Found in Australian Halite

Using transmitted light petrography and UV-visible light petrography, the authors analyzed primary fluid inclusions and their contents in 830-million-year-old halite from Australia's Browne Formation. The halite was well preserved and allowed them to examine halite crystals from 10 halite beds from core depths between 1,481 and 1,521 m.

Halite crystallizes in the cubic system, with a face centered lattice, f.c.c. (space group Fm3m), its lattice parameter being a 0 = 5.64Å. Halite, along with all the f.c.c. alkali halides, exhibits a peculiar feature: while the ideal surface structure of both the cube {100} (Fig. 2a) and the rhomb-dodecahedron {110} (Fig. 2b,c) are not polar since the lattice …

Helictites

Helictites. Helictites are contorted depositional speleothems which grow in any direction, defying gravity. Some geologists use a fancier term, "non-gravitomorphic". They occur in many forms from tiny filaments (photo #1) through to thick, antler-like forms (photo #6). The intervening photos try to show a progression of thicker threads.
