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 />
