A new biozone for the late Visean miospores<br />
from the Cortaderas Formation in<br />
western Argentina is proposed. It is the Reticulatisporites<br />
magnidictyus-<br />
Verrucosisporites quasigobbettii (MQ) Interval<br />
Biozone. The base of the biozone is defined<br />
by the range bases of Apiculiretusispora<br />
microseta, Dibolisporites disfacies, Reticulatisporites<br />
magnidictyus, Rugospora australiensis,<br />
and Verrucosisporites quasigobbettii.<br />
The upper limit of the MQ Interval Biozone<br />
is marked by the appearance of monosaccate<br />
pollen. Two distinct associations are<br />
recognized; Association A is characterized by<br />
the range bases of the diagnostic species, and<br />
the presence of a group of long-ranging species.<br />
Association B is characterized by the<br />
range bases of Anapiculatisporites austrinus,<br />
Anapiculatisporites kekiktukensis, Apiculatisporis<br />
variornatus, Crassispora kosankei,<br />
Cristatisporites menendezii, Kraeuselisporites<br />
tendatus, Kraeuselisporites volkheimerii, Raistrickia<br />
paganciana, Raistrickia rotunda, and<br />
Spinozonotriletes hirsutus, and is represented<br />
in the upper part of the Cortaderas Formation.<br />

从 植 物 标 本 室 采 集 孢 粉 = Collecting pollen<br />
and spore samples from herbaria. ( 英 文 ). Jarzen<br />

A properly documented pollen and spore<br />
reference collection is a valuable tool in systematic/taxonomic<br />
studies, paleoenvironmental<br />
reconstruction, forensic palynology, archaeology,<br />
aerobiology and other areas of research.<br />
The collection of pollen or spore samples<br />
is best made from vouchered herbarium<br />
specimens that have been identified by trained<br />
systematists. The collection procedure, although<br />
simple, requires careful attention to<br />
each specimen so that the material collected<br />
contains mature pollen or spores, that the relevant,<br />
associated data are recorded and that the<br />
herbarium specimen is not damaged during<br />
the collection procedure.<br />

古 新 世 Momipites-Caryapollenites 相 关 花<br />
粉 的 新 模 式 标 本 = Neotypes for Paleocene<br />
species in the Momipites-Caryapollenites pollen<br />
lineage. ( 英 文 ). Nichols D J; Ott H L. Palynology,<br />
2006, 30(): 33-41<br />
Neotypes are designated herein for certain<br />
Paleocene species of juglandaceous pollen that<br />
were originally described in 1978. The microscope<br />
slides bearing the holotypes have been<br />
lost, eliminating the possibility of designating<br />
lectotypes and necessitating, instead, the designation<br />
of neotype specimens to stabilize the<br />
nomenclature of the species, which are biostratigraphically<br />
significant. The species for<br />
which neotypes are designated are Momipites<br />
wyomingensis, Momipites waltmanensis, Momipites<br />
ventifluminis, Momipites actinus, Momipites<br />
anellus, Momipites leffingwellii,<br />
Caryapollenites prodromus, Caryapollenites<br />
imparalis, Caryapollenites inelegans, and<br />
Caryapollenites wodehousei.<br />

对 非 酸 孢 粉 处 理 过 程 的 深 入 测 试 = Further<br />
testing of a non-acid palynological preparation<br />
procedure. ( 英 文 ). Riding J B; Kyffin-Hughes<br />

The extraction of palynomorphs from sedimentary<br />
rocks and unconsolidated sediments<br />
has traditionally used hydrochloric acid (HCl)<br />
and hydrofluoric acid (HF) to remove the matrix<br />
by dissolution. The use of these, and other,<br />
acids in palynological preparation requires<br />
significant laboratory infrastructure, and may<br />
produce hazardous and potentially environmentally<br />
damaging waste. An effective technique<br />
of palynomorph preparation using sodium<br />
hexametaphosphate [(NaPO3)(6)] was<br />
recently developed. This technique was initially<br />
demonstrated on a suite of samples of<br />
Early Jurassic to Quaternary age. In this study,<br />
non-acid preparation techniques were tested<br />
on 11 samples of Ordovician, Carboniferous,<br />
Jurassic and Paleogene age from the UK. In<br />
four of the six case studies described herein,<br />
the rock was prepared quantitatively using<br />
both the traditional mineral acid technique and<br />
the (NaPO3)(6) procedure. In the Carboniferous<br />
case study, the two samples were prepared<br />
quantitatively using HCl/HF, (NaPO3)(6), and<br />
hydrogen peroxide (H2O2). In the quantitative<br />
preparations, the concentrations of palynomorphs<br />
can be directly compared. Two nonquantitative<br />
case studies were undertaken using<br />
(NaPO3)(6) only, in order to demonstrate<br />
that this method is of practical utility.<br />
The (NaPO3)(6) and H2O2 methods generally<br />
proved to be as effective as the mineral<br />
acid procedure. However the results from the<br />
three Paleozoic samples proved somewhat<br />
variable. The Early Ordovician sample 1 did<br />
not break down in (NaPO3)(6), and consequently<br />
the palynomorph yield from this sample<br />
was extremely poor, compared to the acid<br />
