Understanding Stratum in Geology, Including Types and Examples
A stratum is a rock layer with a lithology (texture, color, grain size, composition, fossils, etc.) different from the adjacent ones and several form strata.

Understanding Lithological Maps: The Basics
Lithological maps are geological maps with the graphic, spatial representation of rock type, distribution, and other physical features, including that of unconsolidated surficial materials. These
What Is Lithology and What Does It Entail?
Lithology studies physical properties like color, texture, composition, or grain size of visible rock outcrop units, core, or hand samples, including with a low magnification
What Are Lapilli Tuffs and Lapillistones
Lapilli tuff and lapillistone refer to a pyroclastic rock formed from predominantly lapilli-sized (2-64 mm) pyroclasts ejected during an explosive volcanic eruption. These rocks can
Get Insight on What Lapilli Are and Their Types
Lapilli are rock fragments or pyroclasts measuring 2 to 64 mm (0.08 to 2.52 inches) in diameter formed and ejected during an explosive eruption. These
What Is a Pyroclastic Breccia and How Does It Form?
A pyroclastic breccia is a volcanic rock with predominantly angular rock fragments larger than 64 mm (volcanic blocks) set in a finer grain matrix such
What Are Volcanic Blocks and How Do They Differ from Bombs
Volcanic blocks are angular to sub-angular rock fragments measuring more than 64 mm (2.5 inches) in size blasted into the air while in solid form
Meaning and 12 Examples of Lava or Volcanic Bombs
Lava or volcanic bombs are rounded to ellipsoid masses of lava measuring at least 2.5 inches ejected during a volcanic eruption. They get their aerodynamic
What Are Agglomerates and How Do They Form?
Agglomerates refer to the accumulation of coarse volcanic material (clasts, lava) and sometimes country rock fragments with at least 75% bombs set in a finer-grained matrix
