    Financing environmental improvements : a literature review of the constraints on financing environmental innovation by Johnson, Daniel K. N. , Lybecker, Kristina M.

    In an effort to explore the potential for financing environmental innovation, this paper examines different forms of financing and attempts to evaluate their effectiveness. The study considers both public and private forms of funding as well as providing policy suggestions for the support of appropriate financing for eco-innovation.

    JPN-21

    According to the sample information sheet, JPN-21 is a crossite-epidote-amphibole-bearing blueschist. Though mineral identification is somewhat complicated by the fine-grained nature of this foliated green rock, the dominant minerals appear to be quartz, chlorite, and calcite or aragonite, all of which are elongated and strongly aligned.

    KBR13

    Described by Western Minerals Inc. as 'porphyroblastic metasediments/hybrid rocks, interpreted by Eales and his coworkers as metamorphosed 'Red Beds' Formation sediments but conceivably magmatic in origin. The specimens illustrate the range in textures and compositions.' Texturally, this fine-grained thin section is an allotriomorphic, junky intergrowth of larger, roughly rectangular feldspars with granular calcite and chlorite. Opaques are abundant.

    JPN-9

    The crystals in this thin section look somewhat out of equilibrium with the melt. The groundmass is microcrystalline and riddled with plagioclase and pyroxenes, as well as glass. Crystals of the phenocryst population are generally subhedral, with rounded corners and irregular twins. The pyroxenes are frequently rimmed by pyroxenes of differing composition. Plagioclase phenocrysts are of differing generations; the first has cloudy, inclusion-rich cores with fresh rims and the second lacks this core. Both may be concentrically zoned. The pyroxenes in particular tend to cluster in glomeroporphyroclasts. The occasional granular aggregate of calcite can be observed in this sample.

    KBR7

    Plagioclase and clinopyroxene form subhedral, unaltered grains amongst a background of finer-grained, intermingled iddingsite and zeolites. Described by Western Minerals Inc. as an 'interstitial ferrotholeiite, very highly fractionated…textures are similar to those associated with rapidly frozen or highly viscous melts.'

    KBR18

    Elongate plagioclase laths with interstitial clinopyroxene and minor interstitial hornblende and biotite. Classic diabasic texture. Said by Western Minerals Inc. to be the youngest dolerite body in the area and was emplaced at much deeper crustal levels than the gabbros.

  • Thumbnail for SC-7
    SC-7

    The groundmass of this microporphyritic basalt consists of glass and plagioclase microlites. Subhedral plagioclase phenocrysts are roughly aligned and some are concentrically zoned. Subhedral, plucked, clinopyroxene phenocrysts of variable size are less abundant than those of plagioclase.

    JPN-17

    The majority of this thin section is a mosaic of inequigranular, anhedral hornblende and highly-poikilitic k-feldspar. Though a few large, irregularly shaped masses of prehnite are interspersed amidst the hornblende and k-feldspar, most prehnite is concentrated along a single vein that runs the length of the thin section. Some of the prehnite shows anomalous blue extinction.

    SC-6-BL

    Plagioclase, the most abundant mineral in this thin section, grades smoothly in size from groundmass mircrolites to subhedral microphenocrysts. Tiny, equant opaques join the plag microlites in forming the groundmass. Clinopyroxene, the second most abundant mineral, is found as relatively euhedral microphenocrysts. Plucking of the pyroxenes is severe. A fiberous phase is frequently found infilling or perhaps pseudomorphing a rectangular phenocrystic phase.

    AGUNG FL

    The plagioclase crystals in this vesicular basalt display a continuous range of sized from groundmass microlite to sieve-textured, sometimes zoned blocky phenocrysts. The groundmass contains more blocky plagioclase than other lavas from the Bali suite. The pyroxenes are generally subhedral and form glomeroporphyroclasts.

    59-K-91

    This vesicular basalt contains microphenocrysts of olivine and orthopyroxene, both of which are also lesser components of the groundmass which consists mainly of uniformly-sized plagioclase laths. The olivine phenocryst have weak reaction rims. Some plagioclase is zoned and sieved.

    SYH-3D-1

    This thin section consists of several zones. The first, a fine-grained glaucophane schist with accessory sphene and zoisite. Microcrenulations cause the boundaries between individual glaucophane crystals to blur. This zone is abruptly cut by a green, omphacite-rich band. In the third zone, the glaucophane fabric is interleaved with elongate aggregates of omphacite and other accessory minerals.

    This paragonite schist is peppered with euhedral and aggregated clinozoisite. A few phengitic pods with large zoisite grains are found.

    Aligned muscovite crystals form a foliation with anhedral, interlobate, though elongated grains of quartz and k-feldspar. Grain boundaries are irregularly shaped.
