Understanding how faulting and fracturing influence rock permeability, fluid flow, and mass transfer is crucial for hydrothermal mineralization. This volume explores these concepts at the intersections of structural geology, fluid flow, and mineralization research, presenting innovative ideas that challenge existing theories on fracture systems and hydrothermal mineral deposit formation. It also highlights recent advances which show the importance of the development of fracture connectivity in focusing fluid flow.
On 2 October 1995, Dave Johnston disappeared while working in the field at Annagh Head, Belmullet, County Mayo, Ireland. He is believed to have been washed from the shoreline by a freak wave. Dave graduated in 1980 with honors in Geology from Trinity College Dublin, returned in 1984 as a lecturer, completed postgraduate research at Monash University for his PhD on Uranium deposits, then focused on Ireland’s metal deposits and tectonics. His recent papers applied fractal and chaos theory to geological phenomena and mineral deposits.
Dave was an enthusiastic teacher and inspired many of the students and researchers who he taught or worked with. Indeed, many former students now work in a diverse range of geology related industries. He firmly believed that academia could interact and collaborate more closely with industry to their mutual benefit. Thus, the members of the Irish Association for Economic Geology elected him as a council member. As President of the Irish Geological Association, Dave enthusiastically shared geology with the public. He enjoyed chatting with students and colleagues and having geology discussions over a pint after fieldwork. He was a deeply caring individual who made time to help anyone who needed it. Throughout, he remained closely attached to his home and family in North Dublin and considered himself to be very fortunate to be able to do what he loved best, geological research based in the magnificent surroundings of Trinity College.
Dave, a vibrant individual, cherished life through rugby, scuba diving, fieldwork, and travel. He hosted the singing at the ‘Friends of the Irish’ party for years, known for sharing quirky stories and jokes about his odd adventures. These usually involved the series of clapped-out vehicles that he always seemed to own. There was the time his car rolled down a cliff in Donegal, the time his car’s engine went on fire, but because he was late for a meeting at the Lisheen deposit, he threw some water on it and drove on! Anyone who knew or met Dave has a similar story to recount of his various exploits.
This volume on ‘Fractures, Fluid Flow and Mineralization’ is a fitting tribute to his memory. As George Sevastopulo so appropriately said at the conference held in Dublin in November 1997 to commemorate Dave’s life, ‘Dave would have loved to have been here’. He is greatly missed by his former students, many colleagues and friends around the world.
