Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

All about Diabase and Jaspillite Properties
Know all about Diabase and Jaspillite properties here. All properties of rocks are important as they define the type of rock and its application. Diabase belongs to Igneous Rocks while Jaspillite belongs to Sedimentary Rocks.Texture of Diabase is Aphanitic, Granular whereas that of Jaspillite is Banded, Trellis. Diabase appears Vesicular and Jaspillite appears Banded and Glassy. The luster of Diabase is while that of Jaspillite is earthy. Diabase is available in dark grey to black colors whereas Jaspillite is available in red, reddish brown colors. The commercial uses of Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Jaspillite are creating artwork, jewelry.
