Simple craters
Definition
-- bowl-shaped with gently sloping floor
-- smooth inner walls and rim
-- less than 20 kilometers in diameter
Term
Complex craters
Definition
-- The inner walls of the crater interior to the rim have a terraced (platformed) or rough appearance
-- There is a mountain peak, or a range of peaks, near the center of the crater. These are surrounded by a flat floor. E.g., Copernicus - 93 km diameter - near Mare Imbrium Tycho - 85 km diameter - in southern highlands
-- 20-180 kilometers in diameter.
Term
Peak-ring basins
Definition
-- these are distinctive for having a concentric ring of mountains interior to the basin rim
-- diameters of 180-400 kilometers
-- the smaller examples of these types of structures may also be referred to as peak-ring craters
Term
Multi-ring basins
Definition
-- these are the largest impact structures on the Moon
-- they have two or more inner rings of mountains interior to the rim of the basin
-- the basin rim itself has the appearance of an extended circular range of mountains
-- excellent example: Orientale Basin on the lunar farside.
-- multi-ring basins on the Moon tend to have diameters greater than 400 kilometers
Term
Ejecta blanket
Definition
-an exterior deposit of material that surrounds a crater and extends outwards from the crater rim
-the surface is often "hummocky" and uneven in texture
-close to the crater rim the ejecta blanket is thickest and forms a continuous cover of material, while farther out from the rim it breaks up to form a thinner more diffuse cover that merges into the surrounding terrain.
Term
Secondary craters
Definition
-these are small craters which are found scattered amongst the ejecta blanket
-they are much more numerous on the outer part of the ejecta blanket than on the inner part
-in some locations groupings or even chains of secondary craters are seen.
Term
Bright rays
Definition
-these are bright streaks of material that radiate outwards from a crater over distances much larger than the crater diameter
- they are associated only with very young, fresh-looking craters that have well-defined rims.
Term
Breccia
Definition
a rock that is made up of fragments of smaller rocks and material which has been cemented together under conditions of high heat and pressure
Term
Regolith
Definition
-a very rubbly and powdery layer of material that covers both the lunar highlands and mare
-produced by the breakup of the lunar surface by impact events, and by the collision of atomic particles in the solar wind with lunar rocks.
Term
Mare/Maria
Definition
formed by the flooding of dark lava into large impact basins on the Moon’s ancient surface
Term
Basalt
Definition
a dark volcanic iron-rich rock formed by the cooling of lava that erupted onto the lunar surface
Term
Sinuous rilles
Definition
broad meandering channels that are found mostly on the maria, and were carved by ancient "rivers" of lava
Term
Straight rilles
Definition
associated with fracturing - breaking - of the lunar crust
Term

Definition
A volcanic rock common in the lunar highlands which has little or no iron
Term
Crater Density (D)
Definition
D=Number of craters (N)/area (A)
Term
wrinkle ridges
Definition
form on the basalt layers that fill impact basins. thought to be caused by a buckling of the surface layers as the weight causes the basalt to sag.
Term
flow fronts
Definition
smooth scarps which mark the edges of old solidified lava flows
Term
fire fountains
Definition
geyser-like eruptions on the lunar surface that result in the formation of colored glass beads in the regolith
