Embodying masculinity in female dominated research settings: A male reflection of ‘doing research’ in massage parlours

This paper reflects on the male experience of conducting fieldwork in massage parlours; off-street settings where women exchange sexual services in predominantly heterosexual monetary transactions. It examines debates surrounding the desirability of gender incongruence between researchers and their informants. By acknowledging the complex interplay of gender and relations in the field, experiences of power are presented as variable and dynamic rather than fixed. Honest and detailed accounts of interactions with sex workers are used to show the complexities of embodying masculinity in clandestine and feminized spaces. The perceived benefits and limitations of gender incongruence are presented. The need to consciously manage and comprehensively reflect upon the impact of gender, and the complex array of power dynamics in the field is discussed

Magnetic fabrics reveal three-dimensional flow processes within elongate magma fingers at the margin of the Shonkin Sag laccolith (MT, USA)

Unravelling magma flow in ancient sheet intrusions is critical to understanding how magma pathways develop and feed volcanic eruptions. Analyzing the shape preferred orientation of minerals in intrusive rocks can provide information on magma flow, because crystals may align parallel to the primary flow direction. Anisotropy of magnetic susceptibility (AMS) is an established method to quantify such shape preferred orientations in igneous sheet intrusions with weak or cryptic fabrics. However, use of AMS data to characterize how magma flows within the individual building blocks of sheet intrusions (i.e., magma fingers and segments), hereafter referred to as elements, has received much less attention. Here we use a high spatial resolution sampling strategy to quantify the AMS fabric of the Eocene Shonkin Sag laccolith (Montana, USA) and associated elongate magma fingers. Our results suggest that magnetic fabrics across the main laccolith reflect sub-horizontal magma flow, and inferred flow directions are consistent with an underlying NE-SW striking feeder dyke. Within the magma fingers, we interpret systematic changes in magnetic fabric shape and orientation to reflect the interaction between competing forces occurring during finger-parallel magma flow (i.e., simple shear) and horizontal and vertical inflation (i.e., pure shear flattening). For example, we highlight how local crossflow of magma between coalesced fingers increases the complexity of magma flow kinematics and related fabrics. Despite these complexities, the AMS data in coalesced magma fingers maintain their internal flow- and inflation-related fabrics, which suggests that magma flow within the fingers remains channelized after coalescence. Given that many sheet intrusions consist of amalgamated elements, our findings highlight the need to carefully consider element distribution and sample locations when interpreting magma flow based on AMS measurements

Structures associated with the dynamics of granitic rock emplacement (NW Portugal)

This chapter proposes a fieldtrip on NW of Portugal (Oporto metropolitan area), which is a sequence of thematic stops. The stops began on deep crustal level at a magmatic feeder zone—Leça da Palmeira Metamorphic Complex, and follows to a middle-upper crustal level with magmatic features associated with magmatic chamber dynamics of post-orogenic biotite granite (Bt-granites)—the Lavadores granite. Each theme is methodological divided into several sections: short introduc- tory text about each feature highlighted on the outcrops; stop description supported with sketches and photos illustrating what can be really seen at the outcrops; field and/or drawing activity; discussion and conclusion section, focused on new approaches and interpretations of the geological results. On Leça Palmeira Metamor- phic Complex the major issue is a granite-tonalite relationship on a deep shear zone, where a magmatic feeder zone was evolved as a gneissic complex. The Lavadores granite shows all a sequence of mesostructures related with the interaction between mafic microgranular enclaves and the host granite; a morphological potash feldspars (Kfs) classification is used; hybridization mechanism involving Kfs and enclaves motion and an Enclave Disruption Mechanism (EDM) is proposed; feldsphatic plume structure recorded the feeding process into the magmatic chamber
