Le magmatisme de la région de Kwyjibo, Province\ud du Grenville (Canada) : intérêt pour les\ud minéralisations de type fer-oxydes associées

The granitic plutons located north of the Kwyjibo property in Quebec’s Grenville Province are of\ud Mesoproterozoic age and belong to the granitic Canatiche Complex . The rocks in these plutons are calc-alkalic, K-rich,\ud and meta- to peraluminous. They belong to the magnetite series and their trace element characteristics link them to\ud intraplate granites. They were emplaced in an anorogenic, subvolcanic environment, but they subsequently underwent\ud significant ductile deformation. The magnetite, copper, and fluorite showings on the Kwyjibo property are polyphased\ud and premetamorphic; their formation began with the emplacement of hydraulic, magnetite-bearing breccias, followed by\ud impregnations and veins of chalcopyrite, pyrite, and fluorite, and ended with a late phase of mineralization, during\ud which uraninite, rare earths, and hematite were emplaced along brittle structures. The plutons belong to two families:\ud biotite-amphibole granites and leucogranites. The biotite-amphibole granites are rich in iron and represent a potential\ud heat and metal source for the first, iron oxide phase of mineralization. The leucogranites show a primary enrichment in\ud REE (rare-earth elements), F, and U, carried mainly in Y-, U-, and REE-bearing niobotitanates. They are metamict and\ud underwent a postmagmatic alteration that remobilized the uranium and the rare earths. The leucogranites could also be\ud a source of rare earths and uranium for the latest mineralizing events

A critical review of executive coaching research: a decade of progress and what's to come.

This paper aims to summarise the current state of coaching research and to provide a basis for future research which will provide a frame of reference ensuring that research builds on previous studies and adds to knowledge rather than replicating previous findings in innocence. This approach will prevent wasted effort and resources in organisations and research. The paper is divided into three sections. The first two sections review the state of research over the past hundred years, with a greater focus on the past decade when coaching research has accelerated at warp speed. The paper divides the recent research into categories; the nature of coaching, coach behaviour studies, client behaviour studies, relationship studies and executive coaching impact studies. The third section considers the future direction research may take. It identifies key questions which the authors believe should be the focus of future research and highlights the work undertaken to support coaching researchers and published by the Coaching Foundation
