To which Limestone called siliceous Limestone -

The rock tripoli is considered a siliceous limestone, as most of the calcium carbonate has been weathered out or baked out by proximity to a plutonic intrusion.

Kieselkalk - Wikipedia

Kieselkalk is also known as the Helvetic Siliceous Limestone.It has sedimented during the Lower Cretaceous epoch. It can contain up to 40% of very fine (1-10 μm), evenly distributed authigenic quartz crystals. Early diagenetic dissolution of opal sponge spicules led to silica enrichment of interstitial waters, which reprecipitated silica in the overlying horizons, forming tiny quartz crystals ...

Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Siliceous Vs. Carbonate Concrete | Hunker

The primary difference between siliceous and carbonate concrete is the type of material of which each consists. Carbonate concrete consists of aggregate that is primarily composed of dolomite and limestone. Siliceous concrete, on the other hand, consists primarily of sandstone and granite, but also contains silica.
