and 96P4e resemble high-K, peraluminous S-type granitoids (Fig. 3.5b-c). Rb-mobility<br />

may cause a transitional position between volcanic arc and collision-related tectonic<br />

setting (Fig. 3.5f-i). The rock samples show different degrees of REE enrichment with<br />

La N/Lu N = 16.7 (L96M25a), 13.0 (96P4e), and 7.8 (L96A9) (Fig. 3.6c).<br />

The Cretaceous monzogranites from the Central Pamirs, RPZ and northernmost South<br />

Pamirs are all high-K, highly peraluminous S-type intrusions. There is some diversity in<br />

this group, probably due to some element mobility of K and Rb. Nevertheless, some<br />

samples are petrologically identified as S-type monzogranites (e.g. the two mica<br />

granite P7). The subalkaline to alkaline subvolcanic latite-andesite A96S1b has a<br />

metaluminous character (Fig. 3.5a-c). The tectonic classification is heterogeneous from<br />

volcanic arc to collisional setting (Fig. 3.5f-i). In chondrite-normalised REE abundance<br />

diagrams all samples show a concave-upward pattern with the highest La N/Lu N values<br />
