Siliciclastic Sand Photomicrographs

Siliciclastic Sand Photomicrographs with picked coarse-very coarse grain chert and rock fragments, and thin section photomicrographs of siliciclastic grainstones with both open intergranular and leached grainmoldic porosities (blue).

Picked loose siliciclastic grains from a well cutting sample with numerous coarse & very coarse grain rock fragments and chert.
Same as previous photomicrograph but under higher magnification.
Similar to previous photomicrographs illustrating numerous coarse & very coarse grain rock fragments and chert.
Picked loose coarse & very coarse grain rock fragments and chert with terrigenous clay (gray) and solid hydrocarbon residue (black).
Same as previous photomicrograph with terrigenous clay and SHR (black).
Picked loose coarse & very coarse grain rock fragments and chert suggesting a grainstone fabric confirmed by high gas show while drilling.
The blue color represents open intergranular porosity in a siliciclastic grainstone, photographed under plane polarized light (PPL).
Same as previous photomicrograph, but under crossed nicols with gypsum plate (UXN w/GP). Note the rounded and angular siliciclastic grains.
High magnification with blue color represents open intergranular porosity in a siliciclastic grainstone, (PPL). Note the dislocated fractured quartz grain indicating compaction.
Same as previous photomicrograph (UXN w/GP). Note the dislocated fractured quartz grain indicating compaction.
Siliciclastic grainstone with open intergranular porosity (blue) (PPL).
Same as previous photomicrograph (UXN w/GP). Note the rounded and angular siliciclastic grains.
Same as previous photomicrograph but under higher magnification (PPL). Note the lithoclast grain (brown).

Siliciclastic grainstone with open intergranular porosity (blue) (PPL).
Siliciclastic grainstone with open intergranular porosity (blue) (PPL). Note the partially leached feldspar grains and clay coating (brown) on the grains.
Same as previous photomicrograph, (UXN w/GP). Note the open intergranular porosity (dark blue) and partially leached feldspar grains.
Photomicrograph of siliciclastic grainstone (UXN w/GP). Note the compacted siliciclastic grains with silica overgrowth indicating sutured grain contacts.
