Facilities available for archaeological research at JCU.

JCU Archaeology is strongly multidisciplinary with research clusters in three colleges (Arts, Society and Education; Science, Technology & Engineering; and Medicine & Dentistry). Archaeological science is strongly supported by the cross-campus JCU Advanced Analytical Centre and eResearch Centre providing access to high-end instrumentation and high-performance computing respectively. Specialist research laboratories include the Tropical Archaeology Research Laboratory (incorporating initial preparation laboratory, sorting laboratory with wet and dry sections, microscopy laboratory and dehumidified store); environmental isotopes laboratory; U-series and cosmogenic dating laboratory; isotopic clean laboratory; and Tropical Dendrochronology Laboratory.


Tropical Archaeology Research Laboratory

JCU hosts purpose-built archaeology teaching laboratories on both the Cairns (A4.204) and Townsville campuses. A purpose-built archaeology research laboratory opened in 2012 in The Cairns Institute (D3.021). In Cairns the teaching laboratory is adjacent to a microscopy room (A4.205) and dehumidified storage facility (A4.206). The Cairns campus also hosts a simulated fieldwork site and experimental plot for controlled field experiments. 

 

Advanced Analytical Centre Equipment

The Advanced Analytical Centre (AAC) is a central analytical facility servicing JCU research and industry needs across the Cairns and Townsville campuses. The AAC is backed by experienced and professional staff and provides a full range of services from sample preparation through to final analysis and reporting as well as specific, hands-on training in instrument use. Instrumentation and techniques used in archaeology include:

Multicollector-Inductively Coupled Plasma-Mass Spectrometer (MC-ICP-MS) - a Finnegan Neptune, high-resolution MC-ICP-MS. It is equipped with 2 different types of detectors. It has 9 moveable Faraday cups, which can simultaneously collect 9 different masses over a static mass range of 12% (e.g. 7Li to 6Li). This measurable mass range is extended to 17% (e.g. 202Hg to 238U) by an array for 4 ion counters that are attached to one of the Faraday cups, allowing the detection of 13 masses. The ion counters are useful for the measurement of very low signal intensities. The instrument used with either solution-based samples or analysis of solids via laser ablation.

The fish collection currently contains bones from 52 fish representing 35 different species found in the Gulf of Carpentaria which is useful for research in northern Australia, Torres Strait and Papua New Guinea tropical coastal zone. Read more about the fish reference collection here. The extensive mollusc reference collection primarily focuses on northern Australia and southern Papua New Guinea. Our hominid cast collection contains high-quality casts of major human ancestors (e.g. Homo habilisHomo erectusAustralopithecus africanusHomo ergasterAustralopithecus boiseiAustralopithecus africanusKenyanthropus platyopsAustralopithecus afarensisHomo floresiensisHomo neanderthalensisSahelanthropus tchadensisHomo sapiensPan paniscusPan troglodytesSymphalangus (Hylobates) syndactylusGorilla gorillaPongo pygmaeus).

Tropical Dendrochronology Laboratory

The Tropical Dendrochronology Laboratory (TDL) specializes in developing proxies of past climate from the tree-rings and chemistry of tropical plants, including trees and cactus. Dendrochronology uses the width and chemistry of tree-rings that grow in order over time (the oldest rings on the inside, the newest rings closest to the bark) to reconstruct that plant's or site's climate or life history. For columnar cactus that grow spines only from their tops, leaving the oldest spines at the bottom and the newest spines at the top, we use the chemistry of spines to find out how old the cactus is and also to deduce and model past climate (i.e. Acanthochronology). We are especially interested in long records of climate that show climate before CE 1850 (before weather instruments were widespread) and records from the tropics, an important region for many global climate features and a region where these records are relatively rare. The laboratory has several pieces of specialised equipment to help us develop and understand tree-ring and cactus spine records.

 

JCU Library

The JCU Library has an extensive collection of archaeological reference books and monographs as well as subscriptions to a wide variety of key journals. Access to the collection and assistance with research is very ably provided by our archaeology Liaison Librarian Bronwen Forster.
