Stratigraphic note : update on the palynology of the Akbarah and Kuhlan formations, northwest Yemen

Following a preliminary palynological report of two samples from the lower part of
the Kuhlan Formation (Unit A) near Kuhlan village, northwest Yemen (Stephenson
and Al-Mashaikie, 2010), a further seven samples from Unit A, and an additional 22
samples from the underlying Akbarah Formation in the same locality are reported.
The seven new samples from the Kuhlan Formation support the 2165A to 2141A
Biozone age originally suggested by Stephenson & Al-Mashaikie (2010), and the new
Akbarah Formation samples suggest an age not markedly different since
Anapiculatisporites concinnus and Spelaeotriletes triangulus are also present in the
Akbarah Formation (e.g. samples AK-11 and AK-12). This correlation confirms that
the lower Kuhlan Formation and the Akbarah Formation, are likely to be late
Carboniferous in age and equivalent to the lower parts of the Al Khlata Formation of
Oman.
