Mercury's Impact structure inventory

This data set display an inventory of impact structures larger than 100 km on Mercury. The gravity measurements were determined using a amore precise approach of calculating the avearge of multiple profiles along the impact structure.

Variables:

ID: Identification number or the name of the impact structure.

Diam (km): The diameter of the impact structure in kilometers.

Lon: Central longitude.

Lat: Central latitude.

Id_source: Primarly identification source ( Gravity data / DTM/ Mosaic model).

Certainity: Grade of certainity ( Certain, probable or tentative).

Class : Geomorphological classification (complex, central peak basins, peak ring basin, multi ring basins, modified basin).

Terraces: Presence of terraces. 

Rim: Rim preservation state.

Depth [km]: Depth measurements in km.

D/d:  Depth to diameter ratio.

Filling: Presence of volcanis infill.

Smooth plains: Filling classified as part of the smooth plains.

Bouguer_center: Measured Bouguer anomaly (mGal) of LOS gravity model (Goossens et al., 2022) associated with the center of the impact structure.

Bouguer_outer: Measured Bouguer anomaly (mGal) of LOS gravity model (Goossens et al., 2022) associated with the outer area of the impact structure.

Bouguer_rimcrest: Measured Bouguer anomaly (mGal) of LOS gravity model (Goossens et al., 2022) associated with the rim area of the impact structure. 

Bouguer_contrast: Bouguer anomaly contrast (mGal).

Stdev_center: Standard deviation of the Bouguer anomaly in the center.

Stdev_outer: Standard deviation of the Bouguer anomaly in the outer area.

Stdev_rimcrest: Standard deviation of the Bouguer anomaly at the rimcrest.

CC: Crater counts of N(20).

Area: The area of the basin in km².

N(20)/Area: Value that refelcts the relative age of impact structures.

CT_center:  Measured crustal thickness (km) associated with the center of the impact structure.

CT_outer:  Measured crustal thickness (km) associated with the outer area of the impact structure.

CT_rim: Measured crustal thickness (km) associated with the rim area of the impact structure.

Temperature [K]: Crustal temperature of impact structures at 39.4km depth at 3.0 Ga.
