Is there a way to plot a log axis in ListPlot3D (or any 3D graph command)
without using Ticks to explicitly plot log-scale tick marks? Basically I'm
wishing there was a 3D equivalent of ListLogLinearPlot.
In the example below I would like a log-scale on the x axis. I've gotten
around it by plotting the data using ListPlot3D[{{xi,yi,zi}...}] and
explicitly making log scale tick marks using Ticks, but feel there must be a
better way.
Any suggestions would be informative and helpful.

Hi, Tamara,
It seems that your data is in some odd format for 3d plot: 9 items in the sublist.
{1.6109253532158105`, 1.4931577390442954`, 1.4052306981890188`,
1.388296872543274`, 1.3781554168518506`, 1.2474079127007878`,

1.0008671342568338`}
I am not quite sure to have understood your question correctly. If I have got you right, you may try the following:
(* This are three sets of data to show in different types of log plots *)
(* I used instead of yours only to have a usual format {...{x,y,z}...}: *)
DataSet1 =
Flatten[Table[{x, y, (Exp[x] + RandomReal[{0, 5}])*Exp[-y]*y^2}, {x,
1, 10, 1}, {y, 1, 10, 0.1}], 1];
DataSet2 =
Flatten[Table[{x, y, (x^5 + RandomReal[{0, 5}])*Exp[y^2]}, {x, 1,
100, 1}, {y, 1, 15, 0.1}], 1];
DataSet3 =
Flatten[Table[{x, y, (Log[10, x] + RandomReal[{0, 5}])*y^2}, {x, 1,
100, 1}, {y, 1, 5, 0.1}], 1];
(* Here are mappings that you might wish to apply *)
g1[{x_, y_, z_}] := {x, y, Log[10, z]};
g2[{x_, y_, z_}] := {Log[10, x], y, Log[10, z]};
g3[{x_, y_, z_}] := {Log[10, x], y, z};
dataset1 = Map[g1, DataSet1];
dataset2 = Map[g2, DataSet2];
dataset3 = Map[g3, DataSet3];
(* and plot them *)
ListPlot3D[dataset1]
ListPlot3D[dataset2]
ListPlot3D[dataset3]
Hope it helps. Alexei
