“…This doline is lined with loess and, as suggested by Jennings (1975) for other dolines in the area, loess appears to have filled the basal shaft. At present, the cave entrance is at the foot of a slope consisting of reworked loess.…”

“…The limestone is of Oligocene age, and is up to 60 m thick (Jennings 1975). It is extensively karstified, with many dolines often draining into shafts of various depths (Jennings 1975). Soils are usually formed in loess which mantles the ground within and between dolines.…”

The late Quaternary fossil vertebrate faunas from caves and cliff sites in the limestone of Mt Cookson, near Waiau in North Canterbury, are described. These faunas allow documentation of faunal changes in the area, over the last 40,000 years, and reveal differences from other previously studied areas that are related to climate. Pitfall faunas from the numerous potholes dominate the deposits, but three predator-accumulated deposits, attributed to the New Zealand falcon Falco novaeseelandiae, were found. The deposits in Merino Cave and Holocene Hole were studied in detail.Merino Cave had two distinct fossil faunas, from which six radiocarbon dates were obtained, showing that deposition spanned the Otiran Glacial period, between 38,000 yrs BP and 14,000 yrs BP. The older of the two Merino Cave faunas, dated at about 38,000 yrs BP, is the first extensive assemblage for the mid-Otiran period from New Zealand. The moa fauna was dominated by the heavy-footed moa Pachyornis elephantopus, but the stout-legged moa Euryapteryx geranoides, upland moa Megalapteryx didinus, large bush moa Dinornis novaezealandiae, and slender moa D. struthoides were present. Carinates included the following: Eyles's harrier Circus eylesi, adzebill Aptornis defossor, large kiwis Apteryx australis or A. haastii, weka Gallirallus australis, New Zealand quail Coturnix novaezelandiae, Finsch's duck Euryanas finschi, kea Nestor notabilis, laughing owl Sceloglaux albifacies, and owletnightjar Aegotheles novaezealandiae. This assemblage indicates an open shrublandgrassland environment. The younger Merino Cave fauna was deposited between 20,000 and 14,000 years ago, during the last major glacial advance at the coldest time of the Otira Glaciation. Only moa bones were present, and P. elephantopus again dominated the fauna. This late Otiran population comprised larger individuals than did the midOtiran population, indicating mean size of individuals got bigger as the climate cooled.Holocene Hole had a rich deposit of small birds dating from the late Holocene, between 3,000 and 2,400 yrs BP. This fauna was deposited when continuous beech forest clothed the landscape. By then the large emeids P. elephantopus, E. geranoides, and M. didinus had been replaced in the fauna by the little bush moa Anomalopteryx didiformis in association with the large bush moa D. novaezealandiae. New Zealand quail and pipits Anthus novaeseelandiae were absent from the local fauna which was dominated by a range of forest species. However, the presence ofadzebills and Finsch's ducks, both absent in Holocene forests farther west, reflects the low rainfall and seasonal dryness of the area. Several species of petrels were present on Mt Cookson: Mottled petrels Pterodroma inexpectata. Cook's petrel Pterodroma cookii, shearwaters Puffinus sp., and diving petrels Pelecanoides urinatrix.The falcon deposits were dominated by bones of kiore Rattus exulans, and included a few bones of species introduced to New Zealand by Europeans, indicating that most of the remains were deposited in the...

Dolines are considered to be among the most prominent karst formations, which is why they can serve as diagnostic forms of karst. Their spatial distribution and density are important indicators of an area’s degree of karstification, as well as of an overall geomorphological development. The aim of this paper is to determine the spatial distribution and the density of dolines, and also to analyse the influence of geological structure and morphometric features of the terrain (hypsometry, slope inclination, relative relief) on the spatial distribution of dolines in the area of southeastern Velebit. Moreover, for the first time with regards to the Croatian karst, the spatial distribution of dolines was compared with the spatial distribution of entrances into caves in the southeastern Velebit’s area of Crnopac. The data on the dolines’ position were adopted from 1:25,000 scaled topographic maps. All data were digitalised and analysed with ArcGIS 10.1 software in the GIS laboratory of the Geographic Department of the Faculty of Science in Zagreb. The research showed a strong influence of morphometric parameters of the relief on dolines’ density. The most prominent occurrence of dolines is linked with the areas ranging from 1000 to 1200 meters of altitude, slope inclination lower than 2° and the relative relief of 100 – 200 m per km2. Furthermore, the highest density of dolines was recorded in the Jurassic carbonate layers, while it was determined that the zones of main faults do not have a significant influence on the increase of dolines’ density. A high degree of correlation was determined by comparing spatial distributions and density of dolines and entrances into caves.
