Greensand

Layer	2 of 5
Blocks	packed mud, terracotta
Thickness	1–12 m
Above	Upper Coralline Limestone
Below	Blue Clay

Greensand (Maltese: Ġebla s-Safra) is the thinnest of Malta's rock layers: a band of orange-brown sandstone between the Upper Coralline Limestone above and the Blue Clay below. It is only a few metres thick, so in a cliff it reads as a single dark line.

In the world

• Blocks: packed mud, with terracotta beds.
• Thickness: 1–12 m, measured where the layer meets the ground on the geological map.

Where to see it

• The rim of the Xagħra plateau on Gozo, above Wied il-Ħanaq: a band of packed mud one block under the soil, with Blue Clay right below it.

Coordinates

• Xagħra plateau rim: /tp @s -9371 145 -14185

Mining

Unlike vanilla packed mud, the Greensand carries ores.

Trivia

• In an early test build, a mistake made the Greensand about 120 blocks thick under the Dingli plateau: a giant brown band through the middle of the hill. The real layer is only a few metres thick.
