Radiolarian chert

Pillow lava (basalt, greenstone). Radiolarian chert (radiolarites). Graywacke sandstone and shale. Radiolarian chert is commonly associated with mafic flows or tuffs or both.

Radiolarian chert is commonly associated with mafic flows or tuffs or both. Many of the associated flows are spilitized.

Permian strata consist of radiolarian-bearing chert and siliceous shale, and sandstone and shale. The radiolarian chert was deposited below the aragonite compensation depth, but for the most part, above the calcite compensation depth. Deposition of the radiolarian chert marks a change in the tectonic and topographic setting of the Austroalpine rifted continental margin. Chert is in most cases a biogenic rock, it is made of siliceous tests of diatoms, radiolarians, siliceous sponge spicules, etc. Sometimes microscopic fossilized remains of these sea creatures may be preserved in these rocks. The lithification and diagenesis of chert is an elaborate process. In some settings, siliceous ooze is pure enough to lithify into a lightweight, minimally processed rock, called diatomite if composed of diatoms, or radiolarite if made of radiolarians.

The sequence of well-preserved basalts and purple radiolarian cherts was found along the Highway 1083 in the Pha Chert lithology, lithostratigraphy, and ocean plate stratigraphy As previously described, the radiolarian-bearing chert is rhythmically well bedded, ranges from a few centimeters to 10 cm in thickness, and contains a dense abundance of radiolarian tests within a microcrystalline quartz matrix. Chert forms when radiolarian skeletons, silt, and ash settle to the ocean floor together and lithify (turn to rock).
