Located on the nothern side of the Tunulliarfik Fjord. The coastal cliffs of this area consist of black lujavrite with inclusions of poikilitic sodalite-nepheline syenite (naujaite). These inclusions are cut by late hydrothermal albitite veins. One of the largest of these veins is described by Sørensen (1962), and is located close to the shore. It is also the typelocality of tugtupite.
In the uppermost part of this vein, the Be-minerals chkalovite and tugtupite are found. The tugtupite is very scarce at the TL.

The spelling Tutop Agdlerkofia is used in Bøgghild (1899).
