New palynological data from peaty<br />
sediments deposited during the Port Moody<br />
Interstade, at about 18 000 14 C years, indicate<br />
that the environment in the western Fraser<br />
Lowland of British Columbia consisted of<br />
subalpine forest and parkland with abundant<br />
fir and spruce that grew under a temperate and<br />
moist climate, similar to the wetter subzones<br />
of the present-day Engelmann Spruce –<br />
Subalpine Fir biogeoclimatic zone. The moist<br />
conditions interpreted for the Port Moody<br />
Interstade are consistent with recent computer<br />
modelling and earlier palynological data from<br />
unglaciated western Washington State, but<br />
appear to contradict regional Cooperative<br />
Holocene Mapping Project (COHMAP)<br />
reconstructions and some earlier<br />
palaeoenvironmental studies that support dry<br />
conditions. Strong seasonality is suggested as<br />
part of the explanation, with Pacific storms in<br />
summer following the southern margin of the<br />
last Cordilleran ice sheet, bringing abundant<br />
moisture to the study area during the growing<br />
season, but probably not in winter, when<br />
storm tracks were displaced to the south. The<br />
cold and dry anticyclonic winds postulated by<br />
COHMAP were probably also relatively weak<br />
in summer, resulting in stronger expression of<br />
moist Pacific air masses than previously<br />
thought. The timing of the Port Moody<br />
Interstade coincides with that of a short<br />
climatic fluctuation reported from several<br />
other sites in both the northern and southern<br />
hemispheres. These events, if causally related,<br />
suggest a rapidly propagated atmospheric–<br />
oceanic signal.<br />

Palynological analysis of the Chigua and<br />
Maliman formations of Middle Devonian and<br />
Mississippian age respectively, is presented.<br />
They crop out in the Del Volcan Range at the<br />
Rio Blanco Basin in western Argentina. In this<br />
second part, 40 indigenous species of cavate,<br />
pseudosaccate and cingulizonate spores from<br />
both units are illustrated. The species<br />
Geminospora sp. cf. G. tuberculata var.<br />
tuberculata McGregor is recorded in the<br />
Middle Devonian of South America for the<br />
first time. The following species are also<br />
recorded in the Mississippian of South<br />
America for the first time as Crassispora<br />
invicta Playford, Densosporites asperus<br />

species (scolecodonts, paleomicroplankton<br />
and spores) from the Maliman Formation are<br />
illustrated and some of them are also<br />
described<br />

= Palynological characterization of Givetian-<br />
Frasnian deposits in the reference Borehole<br />
section 1-Balneologicheskaya (Southern<br />
Timan). ( 英 文 ). Tel’nova O P. Stratigraphy<br />
and Geological Correlation, 2008, 16(2): 143-<br />
161<br />
A succession of seven palynological<br />
assemblages characterizing the Yuzhnyi<br />
Timan, Taman, Ust-Yarega, Domanik, and<br />
Vetlosyan formations of the southern Timan is<br />
established in the Givetian-Frasnian deposits<br />
recovered by Borehole 1-Balneologicheskaya<br />
and studied in detail. Five individual zones,<br />
which are distinguished within stratigraphic<br />
range of the optivus-krestovnicovii miospore<br />
zone, can be of basic importance for a highresolution<br />
stratigraphic subdivision of the<br />
sedimentation stage under consideration.<br />
Phytostratigraphic boundary corresponding to<br />
the Frasnian Stage base in the East European<br />
platform is substantiated in palynological<br />
aspect.<br />
