Research interests

My research interests encompass the roles of fluids, melts and volatiles (H2O, CO2, halogens, noble gases) in a wide range of geological settings from sedimentary basins at the top of the Earth's crust to the Earth's deep mantle interior.  Saline fluids are important for the transport of metals in solution and can lead to the formation of economically important ore deposits.  Magmatic volatiles are exsolved from melts to form fluids that influence metamorphic processes and the presence of volatiles controls the violence of volcanic eruptions.  

I use a range of geochemical and petrologic techniques to investigate volatiles, fluids and melts, however, much of my research is underpinned by a novel method for high precision measurements of halogens (Cl, Br, I) together with noble gases.   I established this method, which represents an extension of the 40Ar-39Ar geochronological method, at RSES, making the ANU noble gas laboratory one of only two laboratories with this capability globally.  I combine this method with standard noble gas analyses and I have lead its application to fluid inclusions, metamorphic rocks and magmatic glasses.  

Current Research

My current research focuses include the alteration of the oceanic crust (see Fig) and the role of halogens in arc-related magmatic processes.  The unifying aim of these projects is to improve our understanding of global-scale volatile re-cycling processes; that is the extent to which plate tectonic processes have caused volatiles to be exchanged between Earth’s surface reservoirs (seawater, air and sediments) and the Earth’s interior over geological time. 

The Figure shows maps of Ca and Cl in metagabbro from the Mathematician Ridge, NE Pacific: the Ca data distinguish the main minerals and show pyroxene replacement by amphibole and albitisation of the plagioclase.  The concentration of Cl in amphibole varies over short distances as a result of fluctuations in the salinity of the amphibole forming fluids.

Participation in IODP expeditions

I am excited to be joining IODP Expedition 360 at the end of 2015.   The ultimate aim of the expedition titled ‘SW Indian Ridge Lower Crust and Moho’ is to drill through the seismic Moho which separates the oceanic crust from the underlying mantle.   Achieving this objective will provide new information about the extent of lithospheric hydration which has important implications for the structure of the oceanic crust and volatile recycling processes.  Furthermore, extensive core recovery from gabbros in layer 3 of the crust will provide critical information about oceanic hydrothermal root zones.     

Morgan Williams is part of the onshore scientific party of Expedition 357 titled ‘Atlantis Massif Seafloor Processes: Serpentinization and Life’.  Morgan will collect samples in a transect across the Atlantis Field and then measure boron isotopes and halogens to investigate spatial variation in serpentinisation processes and the utility of Br and I (which are involved in several biochemical pathways) as biomarkers.

Previous Research Highlights

Quantifying the extent of brine assimilation by oceanic magmas

Combined analysis of Cl, Br, I, F, H2O and trace elements in magmatic glasses, shows that high salinity brines generated at depths of 2-3 km are the most common source of the seawater components assimilated by oceanic magmas and that there is no evidence for assimilation of seawater or altered oceanic crust close to the seafloor.

The lavas most severely affected by brine assimilation have typically assimilated up to 70 % of their total Cl and 30% of their total water. This is equivalent to a litre of melt assimilating 7 cm3 of a brine with 50 wt % salts (Fig). Combined analysis of Cl, Br and I in magmatic glasses is also proving critical for distinguishing between alternative volatile sources in arc magmas. These methodologies are now being applied to better constrain the fate of halogens in subduction zones.

This work has been reported in a series of publications, see 1, 2, 3.

Serpentinites as a pathway for noble gas subduction

In order to rigorously test the efficiency of the so called ‘Noble Gas Subduction Barrier', we undertook a combined study of noble gases and halogens in seafloor serpentinites and their metamorphosed and dehydrated equivalents preserved in ophiolite sequences in the Italian Alps and Betic Cordillera of Spain.

Fig. a) Antigorite serpentine cut by olivine-titanium clinohumite veins, Erro Tobbio, Italy; b) Spinifex textured olivine in enstatite dominated matrix, Betic Cordiller, Spain. scale bar = 1 cm

The results show that noble gases and halogens have high concentrations in serpentine and preserve relative abundance ratios strikingly similar to marine sediment pore waters.   This is most easily explained if sediment pore waters, as well as seawater, are involved in serpentinisation, which is likely to occur distal to mid-ocean ridges.  Furthermore, while ~90% of the noble gases initially present in serpentinites are lost during eclogite facies metamorphism, the dehydrated olivine-enstatite residue formed by completed breakdown of serpentine (Fig b) retains a noble gas concentration of one to two orders of magnitude more than the mantle.  Serpentinites are therefore established as a major breach in the noble gas subduction barrier.

The ability to subduct chemically inert noble gases in serpentinites (and other hydrous minerals) has significant implications for interpretation of mantle noble gas systematics and our understanding of planetary evolution.  The work on serpentinites from the seafloor to eclogite facies has been published in Earth and Planetary Science Letters and Nature Geoscience and is summarised for a popular audience in Cosmos magazine.

The sources and reactions of mineralising fluids

Noble gases and halogens can provide powerful constraints on the sources of fluids and their acquisition of salinity, which is critical to testing genetic models for ore mineralisation. These methods have been applied to a number of deposit styles including: i) Mississippi Valley-type Pb-Zn-fluorite deposits (e.g. sediment-hosted epigenetic deposits), ii) magmatic porphyry copper deposits, iii) orogenic gold deposits formed under transitional greenschist-amphibolite facies metamorphic conditions, and iv) iron-oxide-copper-gold deposits formed under amphibolite facies conditions. The work has been summarised in chapter 11 of The Noble Gases as Geochemical Tracers, and a single example is given below. 

Iron-oxide-copper-gold deposits are formed from ultra-saline (60 wt. % salt) fluids with contested origin. The origin of the fluids has significant implications for exploration, but the relative importance of magmatic fluids and evaporite dissolution remain hotly debated. The figure shows combined halogen (Cl, Br, I) and noble gas data for fluid inclusions in mineralisation-related quartz veins from the Ernest Henry deposit, in the Mt Isa Inlier of Australia.  Basinal fluids that have dissolved halite are distinguished by low 40Ar/36Ar, low Br/Cl and low I/Cl. In contrast, magmatic fluids (which appear to have a similar range of salinities) are characterised by highly radiogenic noble gas signatures, including high 40Ar/36Ar, and mantle-like Br/Cl and I/Cl (see Fig). 

The Ernest Henry data shows that both magmatic fluids and evaporite dissolution can be involved in mineralisation (Fig). However, on a regional basis, the magmatic noble gas signature is well preserved in CO2-rich fluid inclusions associated with barren carbonate veins and albitisation in the Mary Kathleen Foldbelt, and it is not observed in all of the regions ore deposits.  Therefore the presence of magmatic fluids does not guarantee the formation of an iron-oxide-copper-gold deposit, but regional intrusions are important heat engines for driving fluid advection that can lead to mineralisation. It appears that within this framework saline fluids of either magmatic or basinal origin can become ‘mineralising’ by interaction with Cu-rich lithologies.
