Around me spreads a maze of serpentine lanes and zigzagging avenues, of gabled roofs and stone apartment houses whose ocherous
reds and ashen grays harmonize with the pastel hues of the limestone hills defining the northern limits of the city.
Iron oxide and hydroxides present in ferruginous clays, or added in the form of ocherous
earths, for example will, on firing under reducing conditions, form spinel phases which are predominantly black in colour.
Once through this false bedrock, soil samples were taken as deep as 6 feet below surface and often contained abundant ocherous
red-orange soil at the bedrock interface.
Reportedly the specimens come from a near-surface zone of an ore deposit, so we may hope that later ones, found farther down, will not have the white to ocherous
gunk on them and may be fresher-looking.
Pic flashes forward 17 years to March 2000 and the slightly ocherous
tones of the preceding reels give way to sharp, bright colors.
Through the wood smoke and dust and swirl of car exhaust the late sun took on an ocherous
radiance, the red light washing over the grunged and pitted streets.
