Here is an example of geological map in quadrangle V-20. The units are classified as (1) tessera material, (2) plains materials, (3) materials of coronae and (4) materials of domes and miscellaneous flows, with structures like ridges, wrinkle ridge and lineations.
Radar global map of the surface of Venus The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990–1994 Magellan mission, is centered at 180 degrees east longitude. The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus.
The surface of Venus has been divided into 8 quadrangles at the 1:10,000,000 map scale, [1] or 62 quadrangles at the 1:5,000,000 map scale. [ 2 ] 1:10,000,000 map scale
The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) [1] that preserves geologic structures for long periods of time.

It is sometimes called Earth's "sister planet" due to their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). The surface of Venus is covered by a dense atmosphere and presents clear evidence of former violent volcanic activity.
In 2022 the Geological Society of America published an edited volume in his honor, with 33 papers: In the Footsteps of Warren B. Hamilton: New Ideas in Earth Science. [4] The first chapter [5] of this book describes how Hamilton's last paper was written; the second applies Thomas Kuhn's model of scientific change to interpreting Hamilton's career.
