摘要

In the present study, the growth rate and colonization delay of yellow Rhizocarpon geographicum species of lichen are recorded to date recent geological activities at four different localities in Himachal Pradesh. The study involved the measurement ofthe largest sized specimen growing on the well-dated monuments. Correlation of size with age, by plotting the measurements on a graph and finding the best fit line, gives the rate of growth of lichens (per year) and colonization delay, the time taken bythe lichen to grow on a surface after its exposure to the atmosphere. It has been found that colonization delay and growth rate in the four localities namely Sanjoli, Kanlog (both in Shimla), Dharamshala and Dalhousie are 24, 68, 50, 86 yrs and 0.73, 0.79, 0.56, and 0.54 mm/yr respectively. Colonization period was also confirmed by the absence of lichens on the recent monuments prior to the calculated dates. The database will be useful to date the recent geological activities in the region.
