|---|---|
| Michelle_596 | Glushinskite, a dihydrate of magnesium oxalate, occurs at the lichen/rock interface on serpentinite colonized by Lecanora atra at Mill of Johnstone, near Insch in north-east Scotland |
| Michelle_719 | The deposit was formed by the weathering of the local Dalradian sequence. This yielded solutions rich in iron, manganese and other trace elements which subsequently ponded, producing a seepage-bog type ironstone. The permeable breccia acted as a channel-way for these supergene iron-manganese solutions. |
| Michelle_720 | The Lecht Mine deposit was formed by the weathering of the local Dalradian sequence. Local oxalate crystallization is found as a result of lichen growth on primary minerals. |
