Join us at the Rice Northwest Museum of Rocks and Minerals for our annual potluck picnic, Sunday, August 12 at noon. Your $10 will go both to your day's museum admission and to your annual membership to the Rice Museum as a GSOC member. This year will be a great time to take advantage of this offer and treat yourself to a tour of this highly esteemed Pacific Northwest treasure.

Our speaker this year is Dr. Nick Famoso, John Day Fossil Beds National Monument Chief of Paleontology & Museum Curator, who will discuss the world-class John Day Fossil Beds. Nick's work has focused on the recovery of mammalian eco-systems after volcanic eruptions such as Mt. St. Helens and the Picture Gorge ignimbrite.

Picnic is potluck style, so board members will bring a main protein-based dish and general members may bring any type of side dish, dessert, or beverage (no alcohol). The Rice Museum is at 26385 NW Groveland Drive, Hillsboro, OR. Hope to see you there!

Investigative Geology: Combining Historic and Paleoseismic Data to Characterize Earthquake Hazard

Dr. Ashley Streig has sixteen years experience in active tectonics, paleoseismology, structural geology and tectonic geomorphology. Her research experience includes the study of active faults and folds, earthquakes and associated hazards, earthquake recurrence, fault behavior, and rupture characteristics. Dr. Streig has investigated pre-historic seismic activity of fault systems around the world, including local studies of the San Andreas Fault, CA and crustal faults along the Cascadia Subduction Zone.

Dr Nancy Price, Portland State University: Addressing Tectonic Questions from the Perspective of Rheology*

*Rheology: the study of the flow of matter

There are two ways in which structural geologists look at the formation of mountain belts and transform plate boundaries. The first is to describe the folds and faults as rocks reacting to events, and to study the deformation and mineral growth as a reaction to these events. The second is to study the material properties and deformations of the rock layers as a response to stress fields, and to explain the formation events in terms of these properties. In effect, the strength and deformation behaviors of the rocks control the formation of the mountain belts and fault zones. This is the perspective of rheology. In this lecture, Price will show examples of viewing rocks from a rheological perspective and interpreting tectonic history in this light.

Dr. Marli Miller, University of Oregon

Author of the New Edition of Roadside Geology of Oregon (2014)

Dr. Miller's research emphasizes the use of small-scale structures to reconstruct the structural and kinematic histories of high strain zones. She is especially interested in the transition from brittle to ductile behavior in these zones at meso- to microscopic scales. Much of Marli's work is in Death Valley, California where she is also involved with tectonic interpretations.

About Roadside Geology of Oregon, Second Edition (Amazon Review) "Geologist, photographer, and author Marli Miller has written a completely new second edition based on the most up-to-date understanding of Oregon s geology. [Dr. Miller's] spectacular photographs showcase the state’s splendor while also helping readers understand geologic processes at work. Roadside Geology of Oregon, Second Edition, is a must-have for every Oregon resident, student, and rockhound alike."

Rock and Mineral Treasures: Geological Digital Photography 

Featuring photos of otherworldly color and beauty from the Rice Museum collection. 

Julian Gray, Executive Director
Rice Northwest Rock and Mineral Museum 

Geologists constantly need to depict rocks, minerals, and fossils for presentations and publications.  Digital photography has extended the range of possibilities in illustrating samples.  One common problem, reduced depth of field at high magnifications, is easily overcome using stacking techniques.  This technique uses sharply focused portions of sequential photographs focused on different slices or stacks to produce a synthesized images in which the subject is crisply focused.  Julian Gray, executive director of the Rice Northwest Museum of Rocks and Minerals, is a geologist and semi-professional photographer who has experimented with stacking techniques and others to produce stunning images.  Julian's specialty is photomicrography.  His images have been published in mineral magazines and books.
