Chemical evolution and origin of granites in the Lachlan Fold Belt
The author has been involved in studying the granites of the Lachlan Fold Belt (LFB) since
1963 with this being the main focus of his scientific studies since 1973. This thesis brings together
many of the publications that have arisen from that work and those 20 papers that are being
submitted for examination are listed in Section 1 (pp. 2-3) and are bound together at the back of this
volume. A complete list of the 114 publications for which this writer is an author is given in Section
10 (pp. 43-51). That list is comprehensive and again includes the 20 papers being examined. The
remaining 94 papers are listed in support of the candidacy. Among those other papers, 37 deal with
various aspects of granite studies, both in the LFB and elsewhere, and the remainder with a variety
of geological and geochemical subjects

Formal total synthesis of (±)-conduramine E utilising the Bryce-Smith-Gilbert photoamination reaction
Utilising a Bryce-Smith-Gilbert photoamination of benzene as a key step, a synthesis of ()-conduramine E was carried out. A highly regioselective dihydroxylation of a cyclic diene was effected utilising Sharpless AD-mix-b

Introduction
Questions which bridge science and religion cross many boundaries, and this is especially the case in schools and other educational institutions. The boundaries that a curriculum puts around different types of knowledge and different ways of constructing knowledge work well in so many ways in education, but they can become barriers to asking and exploring questions that bridge science and religion if they become systematic and entrenched. At the heart of this book and this introductory chapter, there is a belief that a model of the relationship between science and religion that presumes conflict to be the only way in which they can be viewed does neither science nor religion justice

San Jacinto Intrusive Complex: 2. Geochemistry
Rocks from three large (>100^2 km) tonalitic intrusions exposed in the San Jacinto Mountains of southern California show a restricted compositional range of between 63 and 68 wt % SiO_2 for all but volumetrically minor felsic differentiates (with Si0_2≈70 wt %). All rocks with less than 65.5 wt % SiO_2 show linear element-element covariation. Felsic differentiates have characteristics (higher SiO_2, K_2O, Rb, Ba, U; higher and variable rare earth elements) consistent with derivation by in situ fractionation; rocks with between 65.5 and 70 wt % SiO_2 have intermediate characteristics and are interpreted as derived from liquids formed by mixing “primitive” liquids with fractionated liquids within an intermittently recharged, continuously solidifying magma chamber. Mafic inclusions extend the compositional trends of the mafic tonalites to 55 wt % SiO_2. The chemical variations of both inclusions and more mafic tonalites are interpreted as resulting from processes acting before injection of their parental liquids into the observed crustal magma chambers. Effects of chamber processes are minor for all but the most felsic rocks. The major effect of recharge is to buffer the thermal and chemical properties of liquids within the magma chambers, yielding large volumes of relatively homogeneous tonalite. For those elements where the bulk distribution coefficient is between about 0.5 and 2, concurrent recharge and solidification produces rocks that closely approximate the composition of the added liquids. Estimated Rayleigh numbers for these liquids are high (>10^(10)), implying convection throughout much of the solidification history of each chamber. Existence of trace element variations within analyzed rocks imply that convection was not totally efficient at homogenizing the various batches of liquid added to each chamber
Petrology of the Early Cretaceous Sierra Nevada Batholith; the Stokes Mountain region, CA
Previous studies have shown that the early Cretaceous
batholith (130-110 Ma) contains the least chemically and
isotopically evolved lithologies of the composite Sierra
Nevada batholith.
Mapping at 1:24,000 of a 360 km^2 area
in the foothills ESE of Fresno (the Stokes Mountain region;
latitude 36°30') reveals a smoothly continuous range (SiO_2 = 44-78%) of calcic lithologies dominated by norites,
hornblende gabbros, quartz diorites, tonalites and
granodiorites
