Figure 2: Geological map of the websterite in the Alxa area.

(a) No. 1 websterite lens contains high-pressure garnet-websterite. (b) The cross-sections are indicated on the map and show thrust-imbrication. Sample numbers and ages are marked. (c) Stereographic projection with equal-angle plots illustrates East-West-trending and N-dipping foliations. Square=marble, circle=gneiss, triangle=websterite; n is number of plotted data.
