Record #101915:

Lichenometry of neoglacial moraines in Lewis and Tyndall cirques on Mount Kenya, East Africa / William C. Mahaney, John R. Spence.

Title: Lichenometry of neoglacial moraines in Lewis and Tyndall cirques on Mount Kenya, East Africa / William C. Mahaney, John R. Spence.
Author(s): Mahaney, William C.
Spence, John R.
Date: 1989.
In: Zeitschrift für Gletscherkunde und Glazialgeologie. (1989.), Vol. 25(2) (1989)
Abstract: Published in 1992. Develops lichen growth-rate curve for dating later Holocene (<1000 a BP) deposits in this area. Rhizocarpon section Rhizocarpon species was used because of its longevity and relatively consistent size--age relationships. It grows at about 34 mm during first 100 a, slowing to 7.5 mm a⁻¹ thereafter. This growth-rate curve appears satisfactory for dating neoglacial deposits below Tyndall and Lewis glaciers, which have estimated age of 1000 a BP.
