20221117Conductive fractures are open fractures or fractures filled with lower resistive minerals (pyrite), which can be picked out as dark sinusoidal waves on image attlogs (Fig. 5E). Open fractures are significant pathways for hydrocarbons migration and favorable reservoir space for oil accumulation (Khoshbakht et al., 2009).

The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led t

15.10.2022What minerals have no conchoidal fractures? Positive result - the broken surface exhibits a conchoidal pattern. We conclude that the sample is one of only a few of the common minerals that fracture conchoidally - typically quartz, garnet, or pyrite. Negative result - the broken surface does not exhibit a conchoidal pattern.

Pyrite is brittle and has a slightly uneven, conchoidal fracture. It has a hardness of 6–6.5 on the Mohs scale, and a specific gravity of 4.95–5.10. The powdered mineral smells of sulfur—a property that is useful for identifying it in the field. This mineral has isometric crystals that usually appear as cubes.

The mineral was homogenised, fragmented and stored in sealed plastic containers; a sample of 200 g of the homogenised mineral was used for characterisation purposes.

Most fractures are irregular and nondiagnostic, but some, like conchoidal, even, and splintery fracture can be helpful in identifying minerals. Olivine, garnet, and quartz are well known for their conchoidal fracture (which is the typical fracture pattern you see when you break nontempered glass – a clamshell-like appearance). MINERAL GROUPS

Fracture is a break in a mineral that is not along a cleavage plane. Fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral. Minerals may have characteristic fractures ( Figure below ). Metals usually fracture into jagged edges. If a mineral splinters like wood, it may be fibrous.
