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 />

D M; Jarzen S A. Palynology, 2006, 30():<br />

111-119<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 />

J E. Palynology, 2006, 30(): 69-87<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 />
