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 …

We present a number of features and parameters that halite must possess to be considered a robust archive for retaining primary gas contents. Halite from highly concentrated brine (∼10.6 seawater enrichment; McCaffrey et al., 1987) starts by forming cumulate crystals at the brine-air interface as floating individuals or rafts (Hovorka, 1987 ...

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.

The tabular shape of the NaCl crystals was confirmed by the SEM in Fig. 3A, which illustrates that the crystal plateau height does not exceed the droplet height. Most of these crystals exhibited one edge that was less than 1 mm away from the initial contact line and the central substrate region was free from such distinct salt crystals.

Habit, a property closely related to crystal shape, includes shape and size of crystal faces, how forms combine, how well developed different forms are, and the way multiple crystals grow together. Habit, thus, is the characteristic appearance a mineral can have. The photos in Figure 3.16 show some contrasting examples.

The banded halite represents more tranquil depositional conditions in a brine pool. Through a comparison with the occurrence of halite in the salinas of Baja California, one might postulate that hopper-crystals were deposited in a standing water-body. Desiccation of the shallow pools led to solution and reprecipitation of clean halite crystals. 710
