Bolboforma from Leg 105, Labrador Sea and Baffin Bay, and the chronostratigraphy of Bolboforma in the North Atlantic [PDF]
, 1989 The genus Bolboforma, first described by Daniels and Spiegler (1974), is a problematic group of calcareous microfossils. Solbaforma is most probably a planktonic cyst (Rogl and Hochuli, 1976) having protozoan or algal affinities (Poag and Karowe, 1986 ...

Geochronology of the Phanerozoic granitoids in northeastern China
, 2011 Northeast (NE) China is characterized by immense volumes of granitic rocks, exposed over an area of ∼200,000 km 2 . Although the precise geochronological framework was not clear, it was considered that most of them were emplaced during the Paleozoic ...
